The 2015 Hyundai Genesis is offered with a choice of rear-wheel-drive or new HTRAC® All-Wheel-Drive (AWD) configurations. The new HTRAC AWD system was developed as a multi-mode system, providing an electronic, variable-torque-split clutch with active torque control between the front and rear axles. The system is very lightweight at 165 lbs.
The driver-selectable HTRAC Normal and Eco modes help provide confident control in all-weather conditions. The Sport setting gives a more agile feel by sending more available torque to the rear wheels, for a sporty rear-drive dynamic feel when desired. Further, to maximize efficiency, the system can direct more available torque to the rear wheels during steady-state highway cruising for reduced drivetrain frictional losses and noise. This system has a wider range of torque distribution variability than many competitive systems and has been tuned to variable conditions such as straight-line acceleration, medium- and high-speed cornering, and hill-starts. All modes are programmed in concert with Hyundai Genesis’ Intelligent Drive Mode select.
The heart of the Genesis 5.0 is the award-winning 5.0-liter Tau V8 engine producing 420 horsepower at 6,000 rpm and 383 lb. ft. of torque at 5,000 rpm. The Tau V8 engine family has been named to Ward’s prestigious Ten Best Engines list three times. With high-pressure direct injection for impressive power, low emissions and superb efficiency, this latest version of the Tau V8 benefits from an optimized intake runner length, enhanced timing chain for reduced friction and NVH, low-torque exhaust manifold, increased compression ratio and upgraded multiple-injection mapping. These enhancements combine to produce a flatter torque curve at lower rpm for even better driveability.
The Tau’s high 11.8:1 compression ratio increases thermal efficiency and output. The Tau also has a rigid bed plate for improved block rigidity and lower NVH (Noise, Vibration, and Harshness), as well as camshaft carriers and a roller timing chain to improve valvetrain stability.
Even more, this V8 offers Dual Continuously Variable Valve Timing (D-CVVT), a tuned variable induction system, and low-friction coatings on piston skirts. This Tau engine will also run on regular fuel with only a small reduction in peak power, and no negative driving effects, whenever desired.
The Tau 5.0-liter V8 is mated to an eight-speed automatic transmission. This Hyundai-developed transmission offers enhanced shift logic and speed, better acceleration, sport-mode mapping, shifting smoothness, and transmission efficiency. All eight-speed transmissions include SHIFTRONIC® manual shift capability with conveniently-located steering wheel paddle shifters to enhance shifting ease during spirited driving.
The Hyundai Genesis 3.8-liter direct-injected Lambda engine has also been further optimized to deliver a flatter overall torque curve at low rpm for enhanced driveability. Thoroughly improved for the new Genesis, this engine includes a three-stage variable intake system, triangular-pattern fuel injector for improved combustion, an air-gap exhaust manifold for better NVH, and an upgraded cylinder block with a variable-vane 2-stage oil pump for reduced parasitic losses. In keeping with its 5.0-liter V8 sibling, the Genesis 3.8-liter Lambda engine utilizes direct-injection and produces 311 horsepower at 6,000 rpm and 293 lb.-ft. of torque at 5,000 rpm. It also has a high compression ratio of 11.5:1 for greater thermal efficiency. The Lambda engine will run on regular fuel with only a small reduction in peak power, and no negative driving effects, whenever desired by the owner.
The 3.8-liter engine also has Dual Continuously Variable Valve Timing (D-CVVT), variable induction, an all-aluminum block and heads, steel timing chain and iridium-tipped spark plugs. Besides horsepower and torque gains, direct-injection technology produces a significant reduction in emissions.
All 3.8-liter engines are coupled to the same eight-speed automatic transmission design as the Hyundai Genesis 5.0. This Hyundai-developed transmission offers enhanced shift logic and speed, better acceleration, sport-mode mapping, shifting smoothness, and transmission efficiency. All eight-speed transmissions include SHIFTRONIC® manual shift capability with ergonomically-placed paddle shifters for spirited driving with manual shifting.
