Even more, this new V8 still offers all of the premium engine technology from the 4.6-liter V8, including Dual Continuously Variable Valve Timing (D-CVVT), a tuned variable induction system, and low-friction diamond-like coatings (DLC) on piston skirts, rings and tappets. Even with these impressive power increases, fuel economy is estimated at 16 mpg city and 25 mpg highway, nearly matching the 4.6-liter V8 (17 mpg city/26 mpg highway). As an additional point of interest, this same 5.0-liter Tau V8 with eight-speed transmission will replace the current 4.6-liter V8 as the standard powertrain in the 2012 Hyundai Equus premium luxury sedan, on sale this summer.
The Tau 5.0-liter V8 is coupled with a new in-house eight-speed transmission. This new Hyundai-developed transmission adds two additional ratios to enhance acceleration, shifting smoothness, and transmission efficiency by six percent over the former six-speed. All eight-speed transmissions will include SHIFTRONIC® manual shift capability. This new eight-speed transmission is the first offered by a non-luxury branded manufacturer.
Hyundai-developed eight-speed automatic transmission
In keeping with Hyundai engineering philosophy, the R-Spec also will include more aggressive chassis tuning, matching its corresponding powertrain enhancements for optimal dynamic balance. For enhanced body roll control, front stabilizer bar diameter has been increased from 25 mm to 26 mm, and rear diameter from 18 mm to 19 mm over the 4.6 model. R-Spec will offer a unique sport design 19-inch alloy wheel with premium machined finish and optional Michelin Pilot Sport PS2 summer performance tires. The R-Spec steering calibration has been matched to this unique wheel and tire combination for optimized performance and driving refinement expectations in this segment. To complete the performance package, front brake rotors have increased from 13.0 inches to 13.6 inches over the 2011 4.6 model.
In addition to the more aggressive styling cues for all 2012 Genesis models, R-Spec will offer unique headlights with dark chrome inserts for a more distinctive front appearance. An R-Spec trim designation badge has been added to the rear deck, and black R-Spec embroidered floor mats daily remind the driver of the performance that awaits behind the wheel. Genesis R-Spec only will be offered in three sport-oriented exterior colors: Black Noir, Titanium Gray, and Platinum Metallic, each with Black leather interior and an all-black leather steering wheel for a differentiated sport appearance from the 4.6 model.
DIRECT INJECTION LAMBDA 3.8-LITER ENGINE
In keeping with its 5.0-liter V8 sibling, the Genesis 3.8-liter Lambda engine will receive direct injection (GDI) technology, boosting its output 15 percent from 290 to 333 horsepower, an impressive gain of 43 horsepower with no increase in displacement. In addition, peak torque rises from 264 lb.-ft. to 291 lb.-ft., a generous increase of 27 lb.-ft. from the same 3.8 liters. Compression ratio increases from 10.4:1 to 11.5:1 for greater thermal efficiency. This new direct-injected Lambda V6 produces a higher specific output (87.6 hp/liter) than its normally-aspirated premium luxury competitors.

The 3.8-liter engine retains all of the premium technologies that have made it outstanding since the launch of Genesis: Dual Continuously Variable Valve Timing (D-CVVT), variable induction, all aluminum block and heads, steel timing chain, and iridium-tipped spark plugs. Besides the generous horsepower and torque gains, direct injection technology produces a significant reduction in emissions through a 40 percent reduction in catalyst light-off time. Further, a variable vane oil pump has been fitted to precisely match oil pressure with engine lubrication requirements for increased efficiency at all engine speeds. As a result, 3.8-liter GDI fuel economy increases over seven percent from 27 mpg to 29 mpg on the highway.
