Volvo’s new VEA family of four-cylinder engines starts production

As a result, Volvo has been planning a new range of four-cylinder engines to power their range in the future – the new Volvo Engine Architecture (VEA) – and has spent the last couple of years readying their design – and their facility in Skövde – to start production. And now it’s underway. Together with Volvo’s Scalable Product Architecture (SPA) the new VEA engines will be a core part of every new Volvo before too long, and will replace the five and six cylinder engines Volvo currently uses and will provide more power than current six-cylinder engines with economy and emissions better than current four-cylinder engines.

Tomorrow’s world: Fiat's MultiAir engine tech

By Jesse Crosse Motor Industry 14 October 2009 16:50 Fiat this year launches what it claims is a big step forward in variable valve timing: MultiAir. It's the first time that a manufacturer has made a properly variable valve system a production reality, and will slowly be rolled out across most of Fiat's and Alfa's car ranges.How does Fiat's MultiAir vary from existing variable valve timing (VVT) systems?Current VVT systems rely on mechanical systems to open and close the valves. Engineers have long understood the benefits of changing valve opening and closing times to tweak an engine's power and emissions performance, depending on the need for power or parsimony.Valves are an engine's nose and mouth – it inhales through inlet valves and exhales through exhaust valves.

Driven: Mercedes-Benz C-Class

Just over 25 years ago, in November 1982, Mercedes Chief Designer Bruno Sacco introduced his new 'baby' 190, codenamed W201. Billed as the new compact Mercedes, it was a successful model that lasted a full ten years until being replaced by the first C-Class (W202). This model – the first with the triangular tail lamps – lasted until 2000 when it was replaced by the W203, a more softly-styled update of the W202 model, with the 'peanut-shaped' linked double headlamps.
