BMW toyota land cruiser (2010)

The Toyota Land Cruiser enjoys a special status in the global market as a vehicle that has proved its tough, lasting and reliable qualities in the most extreme environments. This pedigree has provided the platform for the development of an all-new Toyota Land Cruiser that goes further than ever before to deliver a balance of go-anywhere performance with the poise, comfort and refinement motorists want in normal day-to-day driving.

Makoto Arimoto, new Toyota Land Cruiser's Chief Engineer explains: "Generally speaking, it's considered difficult to achieve both good off-road and on-road performance in the same vehicle. But with the new Land Cruiser, rather than making a half-hearted attempt at offering 50:50 ratio between on and off-road capabilities, we put no less than 100 per cent into developing both. We believe we have succeededSeamless bodywork with minimal panel gaps and a series of aerodynamic enhancements have reduced the vehicle's coefficient of drag (Cd) from 0.37 (current model) to 0.35, which in return supports a marked improvement in high-speed cruising fuel economy.

Aerodynamic efficiency has been improved by reducing the overall height by 15mm, and by introducing front and rear spoilers to channel airflow under the body and direct it cleanly away from the trailing edge of the roof. Deflectors inside the engine compartment correct the flow of air through the radiator grille to reduce turbulence, and the design of the front bumper includes extended corners to push air away from the sides of the front tyres, making for a smoother rearward airflow. Front and rear spats are fitted to manage airflow around the tyres and cut turbulence.

Fitting a fin-shaped aero wiper blade cover and concealing the screen washer nozzles reduces wind noise and further improves aerodynamic performance.

Packaging

To preserve Land Cruiser's agile character, there are only modest increases in external dimensions: the new model is 45mm longer and 10mm wider than its predecessor, with a minimum turning radius of 5.8m.

The wheelbase (2,790mm) and rear overhang (1,075mm) remain the same and clever design of the new front bumper ensures that, although the front overhang is longer by 45mm (at 895mm), the 32° approach angle is unchanged. The departure angle is 25° (24° with electrically modulated rear air suspension) and the ramp breakover angle is 22°.

The corners of the bonnet have been raised, which makes it easier for the driver to precisely locate the vehicle's front extremities when moving in tight urban areas, or navigating close to off-road obstacles.

SAFETY

New Toyota Land Cruiser is equipped with a comprehensive and technically advanced range of active and passive on and off-road safety features. Advanced engineering and sophisticated electronic systems provide a high level of protection while at the same time making driving more rewarding, helping the driver explore and enjoy the limits of the vehicle's performance.

Body structure

Collisions between tall vehicles, such as SUVs, and passenger cars can result in the larger vehicle riding up over the smaller one. To counter this risk, Toyota works to ensure the safety systems of both vehicles involved in a collision can be used to their maximum potential.

To this end, the front crumple zone in the new Land Cruiser's frame is set at a height equivalent to that of an average passenger car. The frame and body are designed to effectively channel and absorb impact energies to help protect all parties involved, even those on the receiving of a collision in a smaller vehicle.

Numerous measures have been taken to control body deformation in a frontal collision, while preserving the structural integrity of the cabin. Reinforcements in the A-pillars have a multi-layer construction between the roof rail reinforcement and cowl to give increased buckling strength and improved energy sustainability when buckled, which helps limit body deformation. In addition, the lower front pillar reinforcements also have a multi-layer construction and high-strength outer rocker panel reinforcements have been introduced.

Using high-tensile sheet steel for the front pillar and roof rail reinforcement improves side collision performance. The roof header reinforcement has a closed top and bottom cross-section, giving added strength and floor cross-members are strategically placed to effectively distribute impact forces - measures which both further help to reduce the risk cabin deformation.

A highly effective multiple load-path cross-member structure channels impact energy from the B-pillars, and inner rocker-to-frame load path brackets carry energy from the outer rocker.

Occupant protection is further enhanced by the foam padded door panels and door trims, reducing the risk of pelvic injuries in a side collision, and crushable door armrests.
