Hyundai Genesis gets exterior design improvements, new direct injection technology for its Lambda V6 engine, new eight-speed automatic transmissions, and enhanced chassis tuning for 2012. 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.
In keeping with its 5.0-liter V8 sibling, the Genesis 3.8-liter Lambda engine will receive direct injection (GDI) technology, boosting its output 15 percent from 290 to 333 horsepower, an impressive gain of 43 horsepower with no increase in displacement. In addition, peak torque rises from 264 lb.-ft. to 291 lb.-ft., a generous increase of 27 lb.-ft. from the same 3.8 liters. Compression ratio increases from 10.4:1 to 11.5:1 for greater thermal efficiency. This new direct-injected Lambda V6 produces a higher specific output (87.6 hp/liter) than its normally-aspirated premium luxury competitors.
The 3.8-liter engine retains all of the premium technologies that have made it outstanding since the launch of Genesis: Dual Continuously Variable Valve Timing (D-CVVT), variable induction, all aluminum block and heads, steel timing chain, and iridium-tipped spark plugs. Besides the generous horsepower and torque gains, direct injection technology produces a significant reduction in emissions through a 40 percent reduction in catalyst light-off time. Further, a variable vane oil pump has been fitted to precisely match oil pressure with engine lubrication requirements for increased efficiency at all engine speeds. As a result, 3.8-liter GDI fuel economy increases over seven percent from 27 mpg to 29 mpg on the highway.
All 3.8-liter engines will be coupled to an in-house-developed eight-speed transmission with SHIFTRONIC and precisely calibrated gear ratios for an overall transmission efficiency gain of six percent. These two additional ratios serve to achieve competing objectives of acceleration and economy without compromise.
For 2012, Genesis’ award-winning Tau 4.6-liter V8 powerplant will now be coupled exclusively with an in-house-developed eight-speed automatic transmission with SHIFTRONIC, adding benefits in acceleration and efficiency. Internal engineering tests estimate this new eight-speed transmission to be six percent more efficient at transferring power than the former 6-speed automatic, increasing highway fuel economy from 25 mpg to 26 mpg. This same 4.6-liter Tau V8 engine was already significantly improved for 2010 with induction and tuning enhancements increasing peak output from 375 to 385 horsepower. A variable intake system, iridium-tipped spark plugs, anti-knock control, and multi-port injection further add to the sophistication of this engine.
Always seeking to enhance the Genesis driving experience, Hyundai engineers have made further refinements to the 3.8 and 4.6 model suspension damping calibrations. These precise adjustments serve to minimize the traditional compromises between handling precision and ride comfort. In addition, body roll control for the 3.8 model is enhanced, with the rear stabilizer bar diameter increasing from 17 mm to 18 mm. Braking is also improved on both the 3.8 and 4.6 models; the 3.8 model front rotor size increases from 12.6 inches to 13.0 inches, while adding by higher performance 4-piston brake calipers, and the 4.6 model front brake rotors increase from 13.0 inches to 13.6 inches for greater fade resistance.
Not content to rest on their laurels, Hyundai’s design team has sought to make a great Genesis exterior design even better for 2012. For the front view, the front grille has been enhanced, a more aggressive front fascia with larger intake openings was developed, and the headlights have been redesigned, adding LED accents and daytime running lights (DRLs). From the side view, the standard 17-inch alloy wheel design has been freshened and the rocker panels have been refined. In addition, the mirrors now incorporate power-folding and puddle lamp functions, while the side window surround now receives a decidedly sporty brushed aluminum finish. From the rear view, the taillights have been redesigned and new dual asymmetrical exhaust tips are more cleanly integrated with a new bumper fascia.
