The all new 2005 Land Rover LR3
A quantum leap in the evolution of the SUV

By Manrico Delcore & Mary Beth Debicki

The all new 2005 Land Rover LR3 (or Discovery 3 as it will be known outside North America) is the first Land Rover to be designed since Land Rover and BMW parted ways in mid-2000 and it represents a re-affirmation of Land Rover’s heritage. At a time when SUV manufacturers are quick to trade off road capability for on road, car-like handling, Land Rover has gone the extra mile and crafted a vehicle that is supremely capable off road and a pleasure to drive on-road. A vehicle that is equally at home in the plains of Africa as on the freeways of LA.

The LR3 is a completely new Land Rover and it introduces more new and cutting edge technology than any SUV ever has. Technology that works to enhance both on road performance and off road capability. Take the suspension for example, front and rear fully independent suspension and air springs give the LR3 a smooth, comfortable ride and precise car-like handling. Yet, when the vehicle detects off road conditions, it cross-links the air springs so that “air displaced by the upward movement of an air spring is transferred to the spring on the opposite side, forcing it down, improving composure and wheel contact with the terrain.” Thus, off road the suspension mimics a traditional beam axle for increased ground clearance, wheel articulation and traction. Who said you can’t have your cake and eat it too!

Progressive, hydraulically operated, power-assisted rack-and-pinion steering gives LR3 precise, solid and responsive steering. Together with the front/rear double wishbone suspension, the LR3 handles like a well mannered sedan and not the 6,000 pound vehicle it is. Driving twisting roads no longer feels like an aerobic exercise, the LR3 tracks precisely and predictably throughout the turns, even at speeds.

And speaking of speeds, this Land Rover goes from 0-60 in 8 seconds, thanks to a Jaguar 4.4 Liter V-8 that cranks out 300 bhp and 315 ft-lb of torque. This powerplant is a modified version of Jaguar’s 4.2 Liter V8. The increase in bore wasn’t the only modification the folks at Solihull performed. The engine’s “mapping” was redesigned to increase torque and to deliver maximum torque at a lower rpms, and because Land Rovers are expected to operate in extreme environments, the Jaguar engine received water-, dust- and mud-proofing. Oil capacity was also increased by nearly 2 liters to insure engine proper engine lubrication even at the extreme angles Land Rovers often find themselves in.

As impressive as LR3’s handling and performance on road are, it is off pavement that this vehicle proves without a doubt that it is pure and true Land Rover. With short front and rear overhangs the LR3 has excellent approach and departure angles, and with all “vitals” tucked-up into the “body-frame”, ground clearance is an amazing 9.5 inches. But it is the way that technological advances have been integrated together that makes the LR3 nearly unstoppable.

The keystone of LR3’s off pavement prowess is Land Rover’s “Terrain Response” system. Land Rover engineers analyzed over 50 different off road terrains and determined the individual engine, transmission, suspension, traction and other vehicle system inputs needed to optimize the vehicle’s performance in each terrain. According to Steve Haywood “we concluded that these [system inputs] can be distilled into just a handful of programs – and those are the settings we offer on Terrain Response”. The driver chooses from among 6 terrains, such as sand, mud & ruts, rock crawling, and the terrain response “black box” configures a number of vehicle systems for optimum performance.

Terrain Response adjusts the air suspension for maximum ground clearance, adjusts the automatic gearbox to optimize gear change points, and alters the throttle map and accelerator pedal response. Traction control and brakeforce distribution are all adjusted to the terrain setting. Land Rover’s patented Hill Descent Control is also adjusted and downhill speed rates vary depending on the terrain, even the center and rear locking differentials use different locking rates depending on terrain.

Sitting behind the wheel felt both familiar and new. The inside is all new, yet is very Land Rover. Large instrumentation, a minimum of switches, and strong vertical lines give the LR3’s fascia a simple and efficient look. There are nonetheless plenty of storage compartments and, yes, drink holders. From the driver’s seat, LR3 feels at once roomy, there’s plenty of elbow room, and compact, all the controls are within easy reach.

LR3 preserves Land Rover’s “Command driving position” and thanks to the stepped roof, the 2nd and 3rd row passengers still enjoy “stadium seating”. The interior is roomy with all seats accommodating “95 percentile” of adults. The cabin is one of the brightest and airiest thanks to the full width glass roof. When not needed, the 2 and 3 rows of seats fold flat into the floor crating an amazingly large and useful flat load space. The passenger doors have grown wider making getting in and out of the vehicle much easier than in previous models.

Mike O’Driscoll, president of Aston Martin Jaguar Land Rover North America summed it up best when he said “[LR3] blends innovative technology and refinement with traditional Land Rover strengths to rewrite the definition of a modern, premium SUV”.
