Hyundai: Efficient powertrains will get us halfway to fuel-economy targets

In an effort to boost fuel-economy for its U.S. lineup, Hyundai will introduce a new strategy named 50/50 where 50 percent of the increase in fuel-economy will comes from vehicle structure and equipment while the rest will come from powertrain efficiency.

For 2007, Hyundai’s vehicle lineup averaged 32.4mpg while trucks averaged 25.5mpg. Under the new proposed fuel-economy regulations, the Korean automakers is required to average 37.5mpg by 2015.

White said that Hyundai will increase fuel-economy through efforts such as aerodynamics, lighter weight, tires with low rolling resistance and electric power steering in place of hydraulic. Electric power steering can add 1mpg said White.

Powertrain wise Hyundai plans on adding a 6-speed automatic transmission within the next two to three years along with direct-injection gasoline engines. Currently, Hyundai’s Veracruz crossover is the only Hyundai car that comes with a six-speed automatic transmission. Hyundai plans on offering the six-speed on all of the U.S. models with V6 engines and most 4-cylinder models.

Hyundai’s 2010 Genesis Coupe will also be offered with a six-speed automatic on both, 4-cylinder 223-hp and V6 310-hp models.
