Infiniti Q50 to offer turbo four-cylinder; diesel possible for U.S.

Infiniti has announced a pair of new engine options for its upcoming Q50 sedan.

Infiniti has revealed plans to expand the engine lineup of its G37-replacing Q50 sedan with an entry-level turbocharged four-cylinder motor. A turbodiesel has also been announced for the European market, although it could end up being offered in the United States as well.

When it first arrives in the U.S. this summer, the Q50 will be available with two powertrain options: a 328-horsepower 3.7-liter V6 carried over from the G37, and a 354-horsepower hybrid setup comprised of a 3.5-liter V6 and an electric motor.

In roughly two years, a powerful and efficient turbo four will be added to the Q50 engine mix, according to Infiniti president Johan de Nysschen. At the same time, the European-market Q50 will gain a turbodiesel motor, though Infiniti says it is also considering offering the mill to U.S. consumers.

Infiniti parent Renault-Nissan will look to its technology partnership with Daimler for both motors, which will be derived from existing units used in the Mercedes-Benz C-Class.

In the past, de Nysschen has additionally confirmed that a performance-oriented IPL version of the Q50 is the works, which will also likely use a turbocharged mill. However, Infiniti has yet to decide whether the IPL will be a mildly upgraded model or a direct competitor to the BMW M3 and Mercedes-Benz C63 AMG.
