Now, I know its a long post  , but after reading it I found it so informative that I thought I would share it with you all. 
A gasoline and a disesel
It has two new engines, one petrol 3.2-liter inline six-cylinder diesel and a 2.2-liter turbocharged four-cylinder.
I6 petrol engine of 233 hp is installed transversely. Its top speed of 200 km / h with acceleration from 0-100 km / h in 8.9 seconds. The consumption figure on the combined cycle is 11.2 litres/100 km. The engine is matched to a new six-speed automatic transmission with manual sequential shift CommandShift Land Rover. The Sport mode is available for drivers who want a livelier performance.
The diesel engine chosen for Freelander 2 is a 4 cylinder 2.2 liter with no less than 160 hp, maximum torque of 400 Nm and 200 Nm of torque from 1000 rpm. Consumption in the combined cycle of 7.5 litres/100 km. It is available also a Diesel Particulate Filter (DPF) option which reduces even more the amount of emissions. The engine is offered with two transmissions: a new gearbox six-speed manual and six-speed automatic transmission used with the gasoline engine (diesel version available from spring 2007).
Wider
The interior of Freelander 2 is a major improvement over the outgoing vehicle. It measures 4.50 m in length -50 mm longer than its predecessor. The rear seats are located in a position slightly higher than the forwards. The boot has a 38% more volume than the previous Freelander (755 liters with the rear seats versus 546 liters).
Its design is continuous, but with a more modern look, keep the clamshell bonnet, the roof and the basic form. The body is a five-door monocoque structure. The suspension is fully independent and uses stability control systems including Roll Stability Control (RSC), helps mitigate the risk of overturning.
The new Terrain Response system, consists of an intelligent system of quattro permanent four-wheel drive improves traction and reduces the consumption figures on the road, or Control Brakes Liberation in Grade (GRC) that holds the vehicle when we release the brake pedal on steep and slippery slopes.
Equipment
Other features and options rare in this class include: keyless starter button bi-xenon headlamps, self-steering front lighting, wipers with rain sensor and the help system in the parking lot (front and rear). The dual panoramic sunroof increases the feeling of space inside the vehicle.
The climate is part of the standard equipment in most versions, and is also available navigation system with DVD satellite color touchscreen. The equipment range includes high sound quality DAB digital radio and Dolby ™ Prologic IIx Surround Sound with fiber optic interconnects. All vehicles have a number of auxiliary audio connection (for iPods and MP3 players).
Designed by Land Rover at Gaydon, near Warwick, Freelander 2 is produced at the Halewood factory in Liverpool.
New 3.2 i6 petrol engine of 233 hp
I6 The new 3.2-liter engine, which will debut on Freelander 2, accelerates from 0 to 100 km / h in 8.9 seconds and its top speed is 200 km / h. With a maximum power of 233 hp at 6,300 rpm and maximum torque of 317 Nm at 3,200 rpm, significantly higher than those offered by the outgoing Freelander's V6 engine (177 hp, 240 Nm), so its benefits outweigh the model above, showing, however, lower consumption figures - 10% less in the combined cycle.
The six-cylinder i6 engine is designed to combine online configuration, theoretically offering greater refinement and smoothness. It is installed transversely, which improves the layout of the passenger compartment and provides additional space in front and behind the engine, optimizing the effectiveness of security systems.
The key to this new compact design lies in the auxiliary transmission system Rear (READ). Conventional motors actuated camshafts and other auxiliary systems (such as the alternator, water pump and air conditioning compressor) using a series of chains and straps protruding from the front of the engine. With the i6's READ system, these components are traction-engine rear side closest to the transmission, which reduces the size of the set. The result is an engine very short, measuring only 600.5 mm long. This feature greatly expands the space of the span of the engine, allowing the i6 transverse installation and assembly around the unit's advanced energy absorbing structure.
The i6 engine has a block, cylinder heads and aluminum backing plate, all structurally optimized to balance low weight and stiffness. Even the cover of the camshafts is structural, allowing it to incorporate the tops of the bearings, further reducing weight.
The i6 employs dual overhead cam 24-valve head (4 per cylinder) to provide the optimum engine breathing. This characteristic is further improved thanks to the changing profile Camshaft (CPS) which includes two intake cam profiles machined completely different in the same tree. The engine management system decides which is the most appropriate profile depending on operating conditions and driver's torque demands. A profile is ideal for driving at low speed low load and the second, marked by increased valve lift is indicated for speed and higher loads. Hydraulic Tappet a provision amending the two-piece cam profiles.
The i6 engine also includes variable valve timing (VVT), which continually modifies the overlap of the valves to offer more power and efficiency with minimal emissions. The combination of CPS and VVT gives curves with a broader torque and power.
In addition, the Variable Intake System, modifying the length of the intake duct and, what is less usual, the volume of the chamber, increasing the torque in the lower and upper end power, further enhances the ability engine breathing. 80% of the vehicle peak torque is available throughout the rev range and 256 Nm between 1,400 and 6,400 rpm.
Aluminum pistons and forged steel connecting rods operate a forged steel crankshaft with seven bearings with surfaces which are hardened by induction. The crankshaft timing gears and startup are incorporated in the flexible plate that sits between the engine and automatic transmission for a more compact package.
The READ system power is received from a gear located at the rear of the crankshaft rib which also drives the oil pump. This, in turn, drives an intermediate gear shaft that drives a shaft which carries two sprockets. The front sprocket drives the alternator and rear handles camshafts in the head, using an inverted tooth chain, and the power steering pump, coolant pump motor and air conditioner compressor grooved through a belt.
The fuel injection system uses four high-precision micro-nozzles per cylinder, each with a diameter of 0.29 mm. Has ability to inject a large volume of fuel when high performance is required - up to 250 cm3/minuto - and act with complete certainty whether the performance requirements are minimal, helping the i6 Freelander 2 to achieve a consumption figure in the cycle 11.2 litres/100 km combined.
The base engine has been developed in Bridgend, Wales - together with the new V8 engine family petrol Land Rover-the i6 has been extensively developed to meet the harsh demands of Land Rover SUV, which has required improving their ability to cope with dust, mud and water and their tolerance of operation in steep angles.
A new 160-hp turbo diesel TD4
The new 2.2-liter turbo diesel TD4 has a maximum power of 160 hp (versus 112 hp 2.0-liter engine of the outgoing Freelander) and maximum torque of 400 Nm (260 Nm compared to the previous model), their performance have been improved. It needs 11.7 seconds to accelerate from 0 to 100 km / h for the manual version (14.4 seconds in the previous Freelander) and its consumption in the combined cycle (7.5 liters per 100 km) is lower than the Freelander Previous (7.7 liters) although its power has increased by 43%.
The TD4 includes cylinders with variable turbulence, fuel injection with common rail "third generation" new Garrett variable geometry turbocharger, cylinder block cooling jacket and balanced shafts installed in the crankcase. The engine complies with the regulations of the EU4 emissions and uses a Diesel Particulate Filter (DPF) that improves performance even more (all data quoted refer to the diesel engine without DPF installed).
The maximum torque of 400 Nm is available at 2,000 rpm. The torque curve is flat, with 80% of the maximum power available from the middle of the rev range and an impressive torque of 200 Nm from 1,000 rpm.
In automatic versions, the Freelander 2 TD4 delivers extra power to push the accelerator pedal depth thanks to the overboost function temporarily increases pressure turbocharger. The new turbocharger with variable geometry (BNT) improves the response at low speeds, providing more mid-range torque in the higher revs and power at the top. The small turbine blades are very light which further reduces turbocharger lag making it virtually undetectable.
The combustion engine is very efficient with piezoelectric injectors, a high pressure fuel injection technology and the turbulence variables, which reduces combustion noise and the pressure inside the cylinder. The piezo injectors precisely control fuel supply system while the common-rail injection "third generation" is capable of injection pressures of 1800 bar, about 30% more than the systems of "second generation". These systems can provide large volumes of fuel at maximum load, which is why these motors offer better performance, and fuel economy-than previous diesel engines.
The new cylinder head optimizes the turbulence throughout the rev range. In many diesel engines, it is necessary to achieve the balance between an acceptable amount of turbulence at low revs avoiding excessive turbulence at high speeds. On the TD4, an innovative system off the inlet ports solves this problem by improving the turbulence and combustion efficiency both at high and low speed.
Each cylinder has two inlet ports. The low speed through air applied at an acute angle to create turbulence at low revs. If it requires a greater flow of gas, opens the second channel, providing additional air without increasing therefore the turbulence.
The block, double shirt is made of cast iron which not only improves its resistance but significantly reduces the noise transmitted, acting as if it were a double glazing. The handle is aluminum alloy while the engine cover, made from lightweight polypropylene, contains a layer of foam to absorb specific noise frequencies. This is a simple but very effective mechanism to reduce by half the engine noise.
The crankshaft, made of rolled steel, is supported by five main bearings. A dual-mass flywheel absorbs engine vibrations. At the other end of the shaft, the torsional vibration damper isolates the valve train and the auxiliaries. To improve even further refinement of the engine, the TD4 uses two balancing shafts, housed in the crankcase, which revolve in opposite directions. These shafts, rotating at double speed as the crankshaft, counteract vibration characteristics of a four-cylinder engine providing a smooth and refined.
The engine, which debuted in 2006 - is the result of the collaboration agreement between Ford Motor Company and PSA, the man behind the TdV6 also installed on the Discovery 3 and Range Rover Sport. As with the i6 petrol engine, the TD4 has been specially developed to meet the demands of wading, running in extreme angles and protection against dust and mud.
The two Freelander 2 engines are available with a six-speed automatic transmission, while the TD4 is also available with manual gearbox six-speed (diesel models with automatic transmission will go on sale in spring 2007).
Both transmissions have been specially developed to meet Land Rover's dual role as a vehicle designed for road and driving across country and transmit power to the intelligent system of quattro permanent four-wheel Freelander 2.
The automatic transmission AWF21 Aisin Warner six-speed is a lightweight and compact unit is characterized by a remote ventilation system, deliberately located above the line wading of Land Rover (500 mm deep). The exceptional quality of change is ensured by a new Control Module fully integrated electronic Transmission.
This module uses different settings change depending on whether you selected the automatic mode or manual CommandShift sports and whether the vehicle uses one of the special Terrain Response programs.
• In sports mode, automatic transmission is programmed to hold the lower gears for longer and reduce facilitating faster acceleration.
• CommandShift allows sequential manual gearshift.
• With Terrain Response special programs activated, apply different settings depending on the chosen mode. The Control Module also manages the transmission torque converter lock varies depending on the mode selected Terrain Response.
The gearbox six-speed manual, available only with the TD4 diesel, is a Getrag M66 designed specifically for Land Rover. This is a four-axis model in which the choice of gear depends on a double cable, which ensures rapid and precise. The dual-mass flywheel carries a single disc hydraulic clutch (250 mm). The system automatically adjusts to maintain constant pedal loads during the lifetime of the vehicle.
The system is fully independent suspension with coil springs, shock absorbers front and rear. The direction of rack and pinion with 2.6 turns between top and cap. It is mounted in the front sub-frame to improve lateral stiffness, is adjustable in height and depth. The front sub-chassis and independent rear are mounted on rubber mounts. The shock absorbers are gas.
The Freelander 2 has 210 mm minimum headroom under the vehicle that you can overcome rocky terrain, sandy or muddy and that help you wade in water up to 500 mm deep.
Drive four
The intelligent system of quattro permanent four-wheel drive has a torque distribution between the front and rear that varies continuously to suit dynamic conditions. Only a small part of the torque is transferred to the rear wheels under normal conditions such as a straight road paved, but in demanding off-road situations, can be transmitted to the rear wheels if necessary, almost all the torque. It is an ideal arrangement that provides maximum grip in difficult conditions, while reducing traction, when it is not necessary, thus reducing rotational losses and fuel consumption.
The torque distribution is continuously adapted. So if you find mud or snow on the road, for example, adjusts torque distribution between the front and rear provide optimum traction and improved safety at all times.
The intelligent 4x4 system has been developed with Haldex, whose central coupling technology continuously modifies the torque distribution between front and rear axle through a hydraulically operated multi-disc wet clutch.
However, Land Rover wanted an electronically-controlled center coupling linking the transmission shaft to the rear differential, which could pre-geared to sleep to reduce the loss of wheel traction in spurts, quickly geared to detect loss of traction and disengaged with the same speed without compromise of stability control systems. The system would also transmit the torque necessary to meet the demands of off-road traction.
The resulting system has been used exclusively on Freelander 2 and proactively engages quickly and quattro permanent four-wheel drive. A new pump high-pressure pre-charge the hydraulic system as soon as you start the engine, enabling the 4x4 traction from the very start. This also reduces the time needed to obtain the maximum torque once it detects a wheel skating - 15 º freely rotating wheel (compared to the 60 th of more conventional units).
The Haldex unit is designed to allow up to 1,500 Nm of torque transmission. An accumulator accelerates the response of the unit. The total transmission torque can be achieved in just 150 milliseconds. In fact, the new Haldex coupling system offers the advantages of a system of quattro permanent four-wheel proactive efficiency and low consumption of a front-wheel drive system.
Adaptability
Terrain Response is a key technology from Land Rover that fits the responses of the engine, transmission, central coupling and chassis systems of the vehicle to the demands of the terrain. Thus, optimizing the transmission and maximizes comfort and traction. It is available as standard on all models except the base
The Freelander 2, the driver can choose any of four Terrain Response settings using a rotary knob:
• Driving General - suitable for driving on the road or undemanding terrain.
• Grass / Gravel / Sand - suitable for slippery conditions, on and off the road.
• mud and ruts
• Arena
Each of these configurations optimized electronic and mechanical controls adapted to the chosen field.
Terrain Response also controls the stability and traction devices as follows:
• Dynamic Stability Control (DSC): designed to help curb the transmission of torque to the wheel that loses traction, although in some off-road situations may be desirable to retain the pair even though that loss. Terrain Response automatically adjusts the DSC to maintain proper pair.
• Electronic Traction Control and antilock brakes: Terrain Response set these control systems to provide optimum grip, braking power and maximum reliability in the field concerned.
• Hill Descent Control (HDC): the latest generation of Land Rover's award-winning technology that automatically limits the speed on the descents using the brakes and improves driver control on slippery descents. The HDC is activated automatically when you select the appropriate Terrain Response programs. The rates of decline vary depending on the selected surface.
Terrain Response also changes the electronic center coupling configurations to optimize the four-wheel traction in difficult conditions. This system, operational, made its debut in 2004 in the Land Rover Discovery 3.
More powerful brakes and larger
The Freelander 2 has ventilated discs front and rear. The large front discs in the model -360 mm and 300 mm petrol in diesel-are "reverse ventilation," which means that air enters the central disc on the bell to go below the rim of this . This approach improves the thermal stability during the halt. Also the dimensions of the rear discs are remarkable - 320 mm in diameter in both petrol and diesel version. The hand brake is a device type disk drum "that uses two pads on each wheel. This provides an outstanding performance in higher than conventional systems from a single disc.
The electronic module, a key element of the control systems of the stability of the Freelander 2 constantly monitors and, if necessary, act selectively on the brakes and engine torque to ensure control over each wheel. Besides reducing the braking pressure as would an antilock brake system (ABS) conventional, the modulator is designed to help generate positive hydraulic pressure that increases the braking force in emergency situations.
Besides the four-way ABS last generation, the modulator also controls Electronic Distribution Brakeforce Distribution (EBD) which balances the distribution of braking force between front and rear, the Emergency Brake Assist ( EBA), which boosts pedal pressure when required maximum braking power, and Cornering Brake System (CBC) which improves the stability of the rear of the car under braking into a curve. It also helps monitor systems Hill Descent Control, Electronic Traction Control and Dynamic Stability Control.
Stability control
The stability control with rollover sensing is the most sophisticated technology to avoid the risk of tipping ever used in a Land Rover. A gyroscopic sensor system allows the modulator-bound mail-compare the level of change of angle of rotation of the body relative to its ideal trajectory. If necessary, rapidly increases the braking force on the outer wheels, widening the turning radius to prevent tipping.
The brake release control on Earrings (GRC) is another innovation, patented by Land Rover, which makes its debut on the Freelander 2. Connected to the Hill Descent Control, progressively reduces the braking pressure, lifting the foot off the brake on steep grades, helping the driver maintain vehicle control.
Wheels and tires
The Freelander 2 is available with a range of wheels and tires with diameters ranging between 16 and 19.
The tires are low pressure cast aluminum and its width is higher than normal. The tires are so versatile that allow them to tackle all the land. Its pressure is 2.2 bar, regardless of size, charge and speed, which simplifies maintenance. The smaller tire-available only in the diesel model is the 215/75R16, while the largest is the 235/55R19 (installed as an accessory only).
Towing Capacity
The automatic model petrol and diesel with manual transmission can carry a trailer with 2,000 kg-trailers exceeding the tare weight of the vehicle, allowing them to carry horse trailers, caravans and many medium size boats. The diesel automatic can tow up to 1,750 kg.
With more than 28,000 Nm / degree of static stiffness, the Freelander 2 has one of the more rigid body in its segment.
It uses a monocoque construction which has been made fuller use of ultra-resistant steel beams in the doors and other reinforcements than any other Land Rover. The dual-phase DP600 steel, which requires a special printing process due to its resistance "is used in the pillars, in doorways, in the side-front and on the dashboard to provide a safety cage lighter.
The twin engine bulkhead vain improves insulation and provides a clean area for components such as the ABS modulator, the brake booster and wiper mechanism.
The length of the Freelander 2 is slightly higher than -50 mm-than the outgoing Freelander. Its width has increased by 109 mm and height 32 mm.
Security
The energy absorbing zones front and rear are designed to absorb as much energy as possible during the impact. Side-impact protection is provided by the beams of the gates of ultra-resistant steel. Other important features include the sleepers of the dashboard that minimize the risk that the A-pillars to collapse on impact and the new system, Roll Stability Control.
The seatbelts include pretensioners for front seats and all versions have seven airbags. The front airbags for driver and passenger are designed to protect the head and chest and are supplemented by side airbags. Integral curtain airbags installed in the roof side structure are designed to protect front seat occupants and rear head injuries and to be thrown in case of rollover. A knee airbag protects the driver against injury from the steering column.
External protection
The Freelander 2 uses only galvanized steel panels double sided as part of treatment and anti-corrosion paint applied ever more sophisticated in a Land Rover. Includes a cosmetic warranty three-year, unlimited mileage anti-corrosion warranty and six years.
As a genuine 4x4, Freelander 2 is designed to withstand impacts and scratches. Vulnerable areas, including thresholds and lower doors, are coated with a rugged thermoplastic material. The cooling system and the engine cowlings have been protected with sturdy structural steel and thermoplastic material, respectively. The bumpers are made of reinforced polypropylene injection molded high pressure material that offers excellent resistance to heat and cold and excellent resistance to impacts and scratches.
Lighting
The standard halogen headlights use polycarbonate lenses impact resistant and scratch (a quality invaluable in driving off-road). The lenses are integrated into the body of the lighthouse to ensure watertightness. Each lamp uses a Gore-Tex membrane that allows for ventilation but not the passage of water and prevents condensation on crossings. Also available H7 halogen bulbs that provide lighting similar to daylight.
Headlamps are also available High Intensity Discharge (HID) that emit a blue-white lighting. The bulbs are filled with a mixture of noble gases (including xenon). The bi-xenon headlamps emit 200% more light than a halogen unit with half the consumption. Their life expectancy is up to 10 times longer. The HID system includes headlamp washers and automatic adjustment to ensure optimum light emission, regardless of vehicle load.
The bi-xenon headlights allow the optional self-directedness Lighting (AFS). The beam rotates in accordance with movements in the direction thus following the path of the curve and improve the driver's vision.
The tail light units form a single piece that incorporates marker lamps, stop lamps, turn signals and reverse lights. Like the headlights are made of polymethyl methacrylate, a material quite resistant to scratches.
Panoramic Roof
The dual panoramic sunroof section is optional. The front section is lifted up and slides back over the second glass panel.
The door mirrors (optional electric folding). The windshield has a thermal windscreen, rain-sensing wipers using infrared technology and washer nozzles with heat.
It has improved its quality and finish and higher quality materials used throughout the cabin. By design is similar to the Range Rover, Range Rover Sport and Discovery 3.
The driving position is high. The rear seats that Land Rover calls "stadium type" provide passengers with a slightly higher than the front so they can enjoy good visibility. The narrow pillars, the dimensions of the front windshield, rear window and side windows, promote the visibility of all occupants.
Your seats
The racks of the front seats are similar to those used in the Range Rover Sport. Is available a full range of fabrics and color combinations, including leather upholstery in top-end versions.
The driver's seat of all models available range of adjustment in six movements, including height. The passenger seat has four-way adjustment. The leather-upholstered front seats have electrically adjustable armrests and optional memory addition of three positions in the driver's seat. Some versions can be ordered with effective two-stage heated seats suitable for colder environments.
The back seat is large enough to comfortably accommodate three adults and includes central armrest in leather upholstered version. With asymmetric division, can be folded down forwards twice to provide a completely flat loading area.
Cargo volume
The trunk provides adequate space for the transportation of luggage or sports equipment, from bicycles to golf clubs. A clever detail is the reversible cover for the cargo space with carpet on one side and impermeable on the other.
The total volume of cargo space is 1670 liters with the rear seats folded and 755 with booster seats (27% and 38% higher respectively than in the previous Freelander). Space has been designed from the outset for maximum versatility. For example, Land Rover has proved even if Roly (one of the big dogs tenants virtual design team) could travel comfortably. The raised floor of the cargo area prevents awkward positions by placing items in the trunk.
Inside the passenger compartment, center console includes cup holders for cans and can accommodate many different packages. Abundant space for transporting objects, including a good glove box and generous door pockets with bottle holders front and rear of 1 liter.
Sound Equipment
On top of audio equipment available with the Freelander 2 is in Dolby Prologic IIx surround sound, 12x40 W amplifier, 12 speakers including subwoofer and 6-CD autoloader. Pets also MP3 format.
Below is a power of 8x40 W with six speakers and subwoofer. The volume control is automatic and varies depending on vehicle speed.
Optionally can be requested headphone jacks in the rear seats so that passengers in the rear seats can enjoy a sound source other than the occupant of the front seats.
The center console comes standard with a specified auxiliary audio jack for connecting an MP3 player, an iPod or another computer. DAB digital radio is available as an option in certain markets.
