Is Subaru Considering a Diesel-Powered WRX STI for Europe

Subaru Tecnica Institute has produced high performance vehicles for over 22 years, but for the first time in its history, there may soon be a diesel-powered Subaru Impreza, tuned for performance, in Europe.


Subaru developed a diesel variant of its famous boxer engine for Europe, which made its debut at the Frankfurt Motor Show back in 2007. Fast forward to January 2009, when it launched the diesel-powered Impreza for Europe, whose 2.0-liter flat four turbocharged engine produced 227 horsepower and 236 pound-feet of torque, mated to a six-speed manual transmission. With Europe's strict emission laws, a diesel-powered STI could be just what Subaru needs to remain compliant.

But will a diesel-powered STI be able to compete with its gasoline-powered stable mate? With a little massaging from Subaru's in-house racing division, it should easily be able to compete. With its low center of gravity, superior fuel economy and low-end torque, a diesel boxer would make perfect sense for the STI. A 2.5-liter turbocharged flat-four gasoline powered STI pumps out 305 horsepower and 290 pound-feet of torque, and we're confident Subaru wouldn't release an oil burning Impreza WRX STI unless it was comparable to the gasoline version.

Just this week, we reported that Subaru greatly improved upon the 2011 STI's handling characteristics. New anti-roll bars, stiffer springs, improved bushings and a lowered ride height all combine for the improved handling. With its improved equipment, the Subaru just lapped the Nürburgring Nordschleife in a record-breaking 7:55. If the rumors from Autocar are true, don't expect a diesel STI to be launched until the Impreza enters its next generation for the 2012 model year.

Mercedes-Benz Anticipates

Mercedes-Benz Anticipates No U.S. CAFE Penalty in 2010
In previous years, Mercedes-Benz occasionally has had to pay penalties because its corporate average fuel economy (CAFE) figure fell beneath standards set by the U.S. government. That will soon change, as the automaker expects to meet the 2010 CAFE standards.

Starting this summer, all of Mercedes-Benz’s six- and eight-cylinder engines will use direct injection, which covers every car the automaker sells in the U.S. According to Dr. Thomas Weber, Mercedes-Benz’s head of research and development, this development played a large part in helping the automaker meet the U.S. standard.

“Even for 2009, we aren’t likely to pay much in the way of penalties,” Weber told Automobilwoche. “From 2010 on, we won’t pay anything. That is clearly our goal.”

Vehicles like the new S400 and ML450 Hybrids will certainly help, but Mercedes-Benz is moving towards using forced-induction engines with smaller displacement. For instance, the new twin-turbocharged 5.5-liter destined for its AMG line is reportedly 25-percent more fuel-efficient than the 6.2-liter V-8 it replaces.

We’re not surprised this is a major focus for Mercedes-Benz. In 2006, the company faced a record million fine, and a similar million fine in 2007. If Weber’s estimations prove correct, Mercedes-Benz has come a long way to reduce fuel consumption while offering customers the power they’ve come to expect.

2011 Mercedes-Benz CLS Preview: Lorinser Previews Tuned Next-Gen CLS

Mercedes-Benz hasn’t even launched its next-generation CLS-Class, but that hasn’t stopped German tuning firm Lorinser from designing a series of cosmetic enhancements for the car.

The new CLS -- which was previewed at the 2010 Detroit auto show with a large sculpture -- is slated to go on sale in 2011, but Lorinser aims to have its own tuned version ready for customers shortly after the launch date. The German tuner already has the bodywork designed, and provided the preview sketch shown above.

According to Lorinser, the body kit is designed to emphasize the new CLS’ masculine and sporty features. A revised front fascia is designed to optimize engine and brake cooling, while swollen fenders allow the tuner to bolt on larger wheels -- we hear the firm plans on offering 21-inch aluminum wheels as an option.

Along with the bodywork, Lorinser will revise the CLS with upgraded chassis, interior trim, and powertrain. We’ve not heard any specifics on any of those improvements, but like any Lorinser product, we imagine the sky -- or the customer’s wallet -- is the limit for modifications.

Lorinser hasn’t detailed exact launch timing for its hopped-up CLS-Class, but noted it will reach dealers in 45 countries -- including the United States -- shortly after the stock version is introduced in 2011.
