From Hyundai press:
The Genesis 4.6 returns this year with 10 extra horses added to the award-winning Tau® V8 engine for a total of 385 horsepower and more standard features from last year’s Technology package. The 10 additional horsepower were added as a running change in 2010 model year and propel the Genesis 4.6 from zero to 60 miles per hour in 5.3 seconds (2010 5.7 seconds). The Tau still produces more horsepower and torque than the powerplants found in the Lexus GS460 and Audi A8. It also delivers more horsepower per liter than any of these V8 competitors. Genesis 4.6 continues to offer buyers the option to use premium or regular fuel. The Tau is rated at 378 horsepower on regular fuel and 385 horsepower on premium fuel and has been one of Ward’s Auto’s 10 best engines for two consecutive years.
For the 2011 model year, Genesis 4.6 has further enhanced its already astonishing list of standard equipment by adding more premium features as standard equipment. Genesis 4.6 now comes equipped with features that were previously optional, such as the Lexicon® 7.1 Discrete surround-sound audio system with 17 speakers, Ultimate Navigation System featuring the intuitive Driver Information System (DIS) with 8-inch screen, smart cruise control, electronic parking brake, cooled driver seat, adaptive front lighting system with HID headlights, and parking assistance system featuring front and rear sensors and rearview camera. The Genesis 3.8 retains its same content and great starting price of $33,000, excluding freight. Genesis was also the North American Car of the Year in 2009.
Genesis is built on Hyundai’s performance-driven rear-wheel-drive architecture. It offers two powertrains, the Lambda 3.8-liter V6 engine and Hyundai’s Tau 4.6-liter V8 engine. The Tau leads all competitors in specific output with 82.2 (regular fuel) to 83.7 (premium fuel) horsepower per liter, respectively. With technology rivaling more expensive luxury sedans, Genesis showcases features such as XM NavTraffic®, Adaptive Front Lighting System (AFLS), Lexicon audio systems and electronic active head restraints.
The Genesis’ rear-wheel-drive architecture was the first application of such in a U.S. Hyundai model. The vehicle boasts a near ideal 52/48 front-to-rear weight distribution for exceptional handling and more refined steering characteristics. The rear-wheel-drive layout also allows engineers to position the car’s front wheels farther forward, delivering outstanding handling and steering performance. Standard Electronic Stability Control (ESC), the industry’s most important new safety technology, further enhances the vehicle’s driving confidence. Genesis reduces interior noise levels and improves ride and handling with a stiffer, lighter body structure. The use of high tensile steel in critical areas in the unibody provides Genesis with high dynamic torsional rigidity and a low body structure weight. Hyundai Genesis also has more interior volume than Lexus LS460 and BMW 750i.
Headlining the Genesis’ performance capabilities is Hyundai’s Tau 4.6-liter V8 engine mated to a ZF® 6-speed automatic transmission with SHIFTRONIC® manual control. The Tau engine is built with flexibility for the future. Future Tau variants may offer larger displacement, forced induction options and other technology enhancements. Genesis also delivers spirited performance through a 3.8-liter DOHC V6 engine that delivers 290 horsepower and 264 lbs.-ft. of torque. To maximize the power spread, the engine uses Continuously Variable Valve Timing (CVVT) on intake and exhaust cam shafts and a new Variable Intake System (VIS) that helps cylinders breathe efficiently at low and high RPM. The better-breathing results in outstanding off-the-line acceleration, passing performance, and remarkable fuel efficiency. The V6 engine uses an alloy block and cylinder heads for lighter weight and thermal efficiency, and features timing chains with no scheduled maintenance. Even with their impressive output, both Genesis engines are also environmentally friendly, achieving Ultra Low Emission Vehicle (ULEV) certification levels.
