2012 Hyundai Genesis 5.0 R-Spec New Tau V8 Engine Producing 429 hp at 6,400 rpm & 376 lb. ft. of Torque at 5,000 rpm

NEW 5.0 R-SPEC: MOST POWERFUL HYUNDAI V8 ENGINE EVER
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.
