Engine
Land Rover's new 5.0-liter, shared with Jaguar, features some interesting firsts. The direct fuel injectors are located smack in the top dead center of the combustion chamber, where the spray pattern can uniformly distribute the fuel for optimal mixing with the air. The spark plug is offset next to it on an angle. Every other current DI engine does it the other way --- plug in the middle. Another cool feature is the cam-torque actuated variable valve timing. When a cam lobe is working against the valve spring to open the valve there's extra resistance that tries to slow the cam down, and then after the lobe passes and the valve starts to close, it wants to speed the cam up. When a cam is rigidly connected to its chain drive these fluctuations can't be noticed, but in variable valve-timing systems that use hydraulic pressure to advance or retard the timing, those pulsations momentarily pressurize one side or the other of the hydraulic adjuster. This system uses little check valves to employ these pressure pulses to move the cam, instead of relying on pressure from the oil pump. It's more efficient and way quicker to respond when the engine is cold.
Autobiography
If the normal Range Rover interior isn't plush enough for you, an Autobiography Package is available on Supercharged models for just $14,500. It features Full Semi-Aniline Leather Seats, Leather Center and Lower Dashboard, Door Panels, Console Sides, and headliner, all of which produces a heady aroma that would make a Harley fetishist swoon. Also included in the package extra wood appointments, the Rear Seat Entertainment with 6 DVD Changer, Climate Glass & 4-Zone A/C, Unique Autobiography 20" 6-Spoke Diamond Turned Wheels, Adaptive Cruise Control, HD Digital Radio and badging.
TFT Display
Cool new flat-screen displays virtual analog gauges, complete with chrome surround reflections simulated. A "Flashlight Mode" setting makes it look like the needle illuminates just the numbers near the end of it, while all other numerals are dim (they can all be bright as well). In off-roading mode, the speedometer slides right to make room for two useful displays showing steering direction, wheel articulation, ride height, and whether the center and rear differentials are locked or not.
