General Motors has announced plans to completely overhaul it’s smallest engine range. This will involve replacing three engine families with a new modular Ecotec design.
Production of the more economical engines will begin around 2015 and it’s expected that by 2020 GM will be producing around two million of these motors per year.
The engines will be developed for global applications but GM hasn’t revealed what models are most likely to receive them. The displacements will range from 1.0-litres through to 1.5-litres in three- and four-cylinder formats. They will feature direct injection, a turbocharger and alternative fuel compatibility. There’s no word on specifications, but GM says the engines will deliver increased fuel efficiency and reduced CO2 emissions. Continue reading “GM announces new Ecotec small engine development” »

Volvo has made a formal commitment to lowering the fuel consumption on every vehicle in its range. How is it going to do it? By eliminating any engine that has more than four cylinders.
It sounds very simple, the Swedish automaker will drop out any five- and six-cylinder engines from its range over the next 10 years. Overall fuel economy figures and C02 emissions will drop and Volvo will earn a reputation as an environmentally conscious car maker. The key to this new initiative comes with the introduction of new three- and four-cylinder powerplants in both gasoline and diesel form.
The new engine family is called Volvo Environmental Architecture (VEA), and the new powertrains will be around 90kg lighter than Volvo’s current engines. In addition to the weight savings, the new engines will improve fuel economy by 35 percent. That’s a serious advancement and Volvo is saying that this is possible without a reduction in performance.
