DETROIT -- Volvo Car Corp. plans to adopt its new four-cylinder engine family in a majority of its models starting next year, said CEO Stefan Jacoby.
The engines will vary in horsepower -- ranging from 150 to 300 -- and "use state of the art-technology" and turbocharging in both gasoline and diesel versions, Jacoby said.
In addition, Volvo will develop a second, smaller engine from the same family with 120 hp to 150 hp. Jacoby said Volvo has not decided whether the new engine will be three or four-cylinder.
The new engine family is called the Volvo Environmental Architecture and will replace Volvo's 10 engines -- a lineup that is "too complex," said Jacoby.
In addition, a gasoline hybrid using the new VEA engine will go on sale in the United States in 2014. Although Volvo showed the hybrid in its XC60 crossover at the Detroit auto show, it hasn't decided which production model will use the technology, Jacoby said.
Volvo may also seek a partner to development the next generation of its smaller cars due in 2017.
The small car replacements include the V50 station wagon that was based on a platform and components from former owner Ford Motor Co., Jacoby said.
The S40 sedan and V50 station wagon were discontinued after the 2011 model-year in the United States because of declining sales.
The next generation V50, which will not be sold in the United States, debuts at the Geneva auto show in March.
The second-generation S40 came out in 2004, and the V50 debuted in 2005.
The first generation S40 and V40 were built by a Volvo-Mitsubishi joint venture in the Netherlands called NedCar.
The vehicles shared parts with Mitsubishi and were built on the same line as the Mitsubishi Carisma sedan and Space Star wagon.
