BMW 5-series is in line for the company's new triturbo diesel engine

Details leaked from a dealer conference held in Holland this week suggest that BMW's upcoming 550dX will be the first recipient of the German carmaker's new high-tech triturbo 3.0-liter inline six-cylinder diesel engine. The new engine, which also is destined for the new X5 xDrive50d and X6 xDrive50d models, is claimed to produce 376 hp and more than 516 lb-ft of torque--some 70 hp and more than 74 lb-ft more than the most powerful version of BMW's existing twin-turbocharged 3.0-liter inline six-cylinder diesel engine, as found in the X5 xDrive40d. The radical new engine, which is rumored to use two traditional exhaust-blown turbochargers in combination with an electrically driven turbocharger to add low-end response, is planned to be offered exclusively with an eight-speed automatic gearbox and four-wheel drive.

Classic vs. Modern, Part One: Porsche 911 Carrera 3.2 or 2012 Kia Rio SX

A recent 220-volt shock administered by the $23K-plus window sticker of a loaded Ford Fiesta rental car made me think about what the same dollars would buy in a classic car, and what the relative cost of ownership would be. My favorite matchup doesn't even require as much coin as said fully accessorized rental Fiesta. The 2012 Kia Rio SX carries an as-tested-by-Autoweek price of $20,745.

Cadillac ELR

Cadillac has revealed the ELR: a production version of the highly-acclaimed Converj concept revealed at the 2009 NAIAS in Detroit. The new luxury coupe will be equipped with extended-range electric vehicle technology – essentially a T-shaped lithium ion battery powering an electric drive unit mated to a a four-cylinder engine-generator, which propels the car when the battery's energy is low. "There's no mistaking it for anything but a Cadillac, an aggressive, forward-leaning profile and proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2," said Ed Welburn, GM vice president, Global Design. Welburn also stated that the Converj concept sparked the idea of combining the desirability of a grand touring coupe with electrification.
