Land Rover introduces new 3.0-liter V6 as its base engine

The upcoming 2014 Range Rover will be available with a new and more efficient 340hp supercharged V6 engine. This new engine choice combines effortless performance and exceptional refinement with enhanced fuel efficiency. The supercharged V6 engine will be offered alongside the 510hp supercharged V8. Both engines will be paired with an eight-speed ZF 8HP70 automatic transmission. The supercharged V6 will replace the naturally aspirated 5-liter V8 in the model line-up.With the new supercharged V6, the 2014 Range Rover will reach 60 mph from rest in just 7.1 seconds*. The supercharged 3-liter 90 degree V6 engine was developed from the existing 5-liter V8. With a peak output of 340hp at 6,500rpm, it offers a strong torque curve throughout the engine speed range, producing maximum torque between 3,500 and 5,000rpm.

The new engine has been engineered to support the full breadth of capability expected from a Range Rover, including extreme off-road tilt angles up to 45 degrees, wading depth of nearly 36 inches (900mm) and towing weight up to 7,716 lbs (3,500kg). The engine's accessory drive is waterproofed, as are the alternator, air conditioning compressor, and starter motor. A pressure die-cast oil pan which features a deep profile and oil pick-up is designed to operate at tilt angles of up to 45 degrees fore/aft. The four-cam V6 shares features a lightweight die-cast aluminum block supplemented with cross-bolted main bearing caps for strength. The valves are controlled by a dual independent variable cam timing (DIVCT) system which is activated by the positive and negative torques generated by the movement of the intake and exhaust valves. This variable timing system features actuation rates of more than 150 degrees per second, to optimize power, torque and economy at all engine speeds. Counter-rotating front and rear balancer weights are engineered into this 90 degree V6 to maximize smoothness and refinement.

Land Rover's Intelligent Stop/Start system helps enhance fuel efficiency in stop and go driving by reducing engine idling under certain conditions which saves fuel and cuts emissions.

Spray-guided direct injection (SGDI) delivers precise quantities of fuel directly into the combustion chambers at pressures of up to 150bar (2175PSI). The fuel is injected in a matter of milliseconds several times during each combustion cycle, creating a more homogenous air-fuel mixture for cleaner and more efficient combustion. A high compression ratio of 10.5:1 further improves fuel efficiency and reduces emissions. The latest-generation Roots-type twin vortex supercharger is mounted in the 'V' of the engine and the charge air utilizes an air/liquid intercooler. A new Bosch engine management system controls all engine functions.

When coupled to a high-strength yet lightweight all-aluminum structure this new powertrain further builds on the efficiency gains of the new Range Rover.
