BMW to offer four-cylinder diesels in North America to improve fuel efficiency

BMW will offer four-cylinder diesel engines in North America as it seeks to improve fuel efficiency and match the performance of its current six-cylinder gasoline engines. BMW is considering diesels in a range of models, including its 1 series, 3 series and 5 series sedans and possibly the X3 crossover and Z4 roadster, said Tom Baloga, vice president of engineering for BMW of North America. "You're going to see it in the 3 series, and the 5 series is a good possibility," Baloga said.

Mercedes-Benz Concept Style Coupe revealed ahead of China auto show

Mercedes-Benz is previewing its eagerly anticipated CLA sedan at an event in Los Angeles this week before providing a more detailed look at the Beijing motor show with the unveiling of the latest in a long line of concept cars, the 2.0-liter, 208-hp, four-cylinder-powered Concept Style Coupe. Pictured here officially for the first time, the heavily sculptured four-door reveals the dramatic appearance that the next junior Mercedes-Benz sedan will carry into North American showrooms in 2013. Advancing the look first established on the F800 Style concept wheeled out at the 2010 Geneva motor show, the Concept Style Coupe is clothed in a four-door body that makes extensive use of concave and convex surfaces to provide its exterior with what Mercedes-Benz design boss Gorden Wagener describes as “an almost fluid appearance and constantly altering depth.” The car has a large gaping grille known to insiders as a soft-nose treatment, striking headlamps with LED graphics, a heavily curved roofline, a shallow glasshouse, a high waistline, frameless doors and a trio of sharply creased lines along its flanks.

2011 Renault Laguna Facelift gets priced

The 2011 Renault Laguna facelift gets priced We guess it’s easier to get your act together as a car maker to price a facelifted car than an all new car. That said, if any business builds a product without knowing its retail price they are in danger of coming unstuck. Still, we applaud Renault for managing to get UK prices for the 2011 Renault Laguna Facelift sorted in a month since the 2011 Laguna appeared at the Paris Motor Show, especially as it took VW eight months to let UK buyers know how much it wanted for the 2011 Sharan.
