Opel and SAIC Unveil Debut Engines at Paris Motor Show image

General Motors and China’s SAIC will unveil at the 2012 Paris Motor Show the all-new engine cradled in the all-new Opel/Vauxhall Junior.

The all-new engine in part of a net-generation engine family with three and four cylinders, ranging from 1.0 to 1.4 liters, with direct injection and turbocharging capability, offering double-digit gains in fuel economy and torque, compared to the outgoing engines without utilizing either. GM also announced that two years from now the U.S. will have a 1.6-liter diesel and gas engine that will replace the current units.

Opel/Vauxhall Junior is a three-door which rivals premium mini cars such as the Mini Cooper, Audi A1 and Fiat 500. The 1.0-liter engine focuses more on fuel economy than power. The model was reportedly part of GM’s plans until the economy collapsed, forcing the company to trim its localized development programs in favor of global products.

Last year GM and SAIC Motor agreed to close form a partnership to develop and build electric vehicles in China. The two companies and their existing Shanghai-based Pan Asia Technical Automotive Centre joint venture will work together to develop structures, architectures and components for battery-powered cars.
