Hyundai’s award-winning Genesis sedan continues its segment leadership with exterior design improvements, a 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 Bridgestone Potenza S-04 Pole Position 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.
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 valve train stability.
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 16 mpg city and 25 mpg highway, nearly matching the 4.6-liter V8 (17 mpg city/26 mpg highway).
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, rear stabilizer bars are a hollow design and diameter has increased 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 Bridgestone Potenza S-04 Pole Position 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.
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.
Maintaining Hyundai’s emphasis on delivering leading safety technology, Genesis boasts world-class active and passive safety features to help both prevent accidents and maximize the well being of its occupants in the event of a collision. Genesis continues the Hyundai tradition of standardizing key life-saving safety technology with Electronic Stability Control (ESC), eight airbags and electronic active head restraints. Adding to this safety leadership for 2012, Genesis adds new daytime running lamps to all models. Further, Genesis offers a newly-developed Lane Departure Warning System (LDWS), available on the 3.8 Technology package, 4.6 and 5.0 R-Spec models.
The manufacturer’s suggested retail price is $46,500.00, the EPA fuel economic estimates 16 MPG city and 25 MPG highway.
