Hyundai-Kia’s powertrain lineup to include new engines and transmissions

Article by Anita Panait, on October 25, 2012

Hyundai Motor Co. and sister company Kia Motors Corp. will be offering additional powertrain setups, featuring more turbocharged gasoline engines and new transmissions in the U.S. and elsewhere, according to their parent Hyundai Motor Group. The group also disclosed that it intends to expand its lineup of diesel-powered vehicles, but it did not reveal in which markets.

The group also did not elaborate when the new engines and transmissions will be available. In 2011, Bloomberg reported that Hyundai was developing a 10-speed automatic transmission for luxury vehicles starting in 2014. Hyundai has introduced eight-speed automatic gearboxes in the Hyundai Genesis and Equus upscale sedans, and six-speed automatic and manual transmissions for its mainstream units.

The group outlined its global future powertrain plans in its announcement last Tuesday, which coincided with the 2012 Hyundai-Kia International Powertrain Conference in South Korea. The recent overhaul of Hyundai's and Kia's vehicle lineups has resulted to introductions of new engine and transmission technologies.

For instance, gasoline direct-injection technologies as well as six-speed automatic and manual transmissions are employed in each brand's lineup, from the Kia Rio to Hyundai Sonata. The group wants to be able to maintain its momentum while rivals like Toyota Motor Corp. and Honda Motor Co., are currently scrambling to bring new, more efficient transmissions and direct-injection engines to the market.

The all new award-winning Hyundai Genesis stays at the top of its segment with the improvements in its exterior design, new and advanced direct injection technology that is powered by a Lambada V6 engine, an all-new set of eight-speed transmissions as well as a well enhanced tuning in its chassis.

Its 5.0 R-Spec model now comes with a direct injection V8 engine of 5.0 liters, a set of 19-inch alloy wheels which are machine-finished, Michelin Pilot Sport PS2 performance tires which are optional as well as sport-tuned steering calibrations, suspension and transmission for elating vehicle dynamics.

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

The core feature of this new version of Genesis is its all-new Tau V8 engine which produces 429 horsepower at 6,400 rpm and 376 lb. ft. of torque at 5,000 rpm. It is deemed to be the most powerful engine from Hyundai ever as it has an 85.8 hp/liter output which is way higher than its premium luxury rival. For the third time in a row, it was named as one of Ward's Ten Best Engines for 2011.

Its 5.0-liter cylinder bore is raised from 92 mm to 96 mm all over the 4.6-liter bore to give an overall displacement of 5.0 liters (5,038cc). The direct injection technology is also added in to support the increased displacement. The high-pressure direct injection system of over 2200 psi also increases power as well as torque dramatically while at the same time reducing the fuel consumption and the emissions.

The compression ratio is also increased from to 11.5:1 from 10.4 for more thermal efficiency as well as output. This type of engine also receives a revised bed plate to improve block rigidity as well as lower the NVH like roller timing chain and camshaft transports to help in improving the stability of the valvetrain.
