Hyundai Genesis

From Hyundai press: Hyundai’s award-winning Genesis sedan continues its segment leadership with exterior design improvements, new direct injection technology for its Lambda V6 engine, new eight-speed automatic transmissions, and enhanced chassis tuning. In addition, a new 5.0-liter direct injection V8 engine is now available exclusively with the 5.0 R-Spec model, which includes unique 19-inch machined-finish alloy wheels, optional Michelin Pilot Sport PS2 summer performance tires and sport-tuned transmission, suspension and steering calibrations for exhilarating vehicle dynamics.

The heart of the Genesis 5.0 R-Spec model is a new Tau V8 engine producing 429 horsepower at 6,400 rpm and 376 lb. ft. of torque at 5,000 rpm. This new Tau V8 represents the most powerful Hyundai engine ever, with a higher specific output (85.8 hp/liter) than its normally-aspirated premium luxury competitors. For 2011, the Tau V8 engine family has again been named to the prestigious Ward’s Ten Best Engines for the third consecutive time.
The 5.0-liter cylinder bore was increased from 92 mm to 96 mm over the 4.6-liter bore for a total displacement of 5.0 liters (5,038cc). In addition to the enlarged displacement, direct injection technology has been added. This high-pressure direct injection system (over 2200 psi), dramatically increases power and torque while reducing fuel consumption and emissions. Compression ratio has been increased from 10.4 to 11.5:1 for greater thermal efficiency and output. The Tau also receives a revised bed plate for improved block rigidity and lower NVH as well as camshaft carriers and a roller timing chain to improve valvetrain stability.

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.

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.
