2011 Buick Regal 2.0 Turbo Now Able to Run On Ethanol

General Motors has released an update on the 2011 Buick Regal's 2.0-liter turbocharged engine that enables it to run on any blend of gasoline or E85 Ethanol. The Detroit automaker claims the Regal's flex-fuel capability is a first for a direct-injected turbocharged production car. There are no performance differences between the standard 2.0-liter turbo engine and its flex-fuel variant, as output remains at 220 horsepower and 258 lb-ft of torque. However, engineers made some changes to allow the engine to run on E85. Given that ethanol needs a richer air-fuel mixture than gasoline to function properly, the flex-fuel engine is equipped with higher flow-rate injectors. In addition, a sensor in the fuel system measures the combination of gasoline and ethanol in the tank (a maximum of 85 percent is allowed of the latter), allowing the engine management system to automatically adjust the mixture to provide the required performance, emissions and fuel consumption. GM's 2.0-liter Ecotec turbo engine also sports a new sand cast aluminium cylinder block, which translates into better durability, less noise and vibration than before. The Regal's engine update is a step towards GM's goal of having more than 50 percent of its production in flex-fuel models by the end of 2012, with the company having already put on the streets more than 5 million flex-fuel cars in the last 15 years.

SAAB to Celebrate its own...Independence Day on February 23rd

A little over a year ago, Saab's future was very much in doubt. GM was looking for a buyer for the Swedish brand and even contemplated closing down the Trollhattan plant. On the other hand, investors weren't exactly anxious to put their money on what they thought was a sinking ship. But, on the 23rd of February 2010, Saab's fate took a surprising turn for the better as GM sold the company to Spyker Cars, saving thousands of jobs and decades of tradition. To celebrate the first anniversary from the sale, Saab will throw a massive party on February 23, 2011, turning its factory in Trollhattan into an entertainment arena. All 3,800 employees will have the day off and will be joined by dealers, suppliers, VIPs and media in celebrating Saab's rebirth as an independent carmaker. The highlight of the event will be the unveiling of a special edition model, most likely the “Independence Edition” of the 9-3 Cabriolet. It might also be a good occasion to show the employees the concept car that Saab will premiere at the Geneva Auto Show. This car will be the starting point for the future compact Saab hatchback, which will be positioned beneath the 9-3 model range. But Saab has other reasons to celebrate as well. “We’ve triggered the biggest new product offensive in Saab’s history with the launch of the 9-5 Sedan and the 9-4X crossover, the introduction of the 9-5 SportCombi later this year, and the arrival of a new generation 9-3 range next year,” said Saab's CEO Jan Ake Jonsson. Who would have dared thinking about that a year ago? By Dan Mihalascu

Chevrolet Plans to Introduce a Limited Edition Camaro Every Six Months

Camaro fans will be happy to know that the bow-tie brand plans to introduce a limited edition version every six months, in an effort to create more hype around its pony car and of course, further increase sales. According to an Automotive News report, Chevrolet will not only revive various nameplates from the past, but will also introduce some brand new ones to the market. “Our plan is to keep evolving the Camaro,” said Al Oppenheiser, chief engineer for the Camaro. “That is the beauty of the Camaro. It has so much of a rich heritage that we can put together the right combination of content. We have a lot of rich names to choose from.” According to Oppenheiser, the upcoming models will follow a similar formula to the 2012 Camaro ZL1 that borrows its moniker from the 1969 Camaro ZL1, which at the time was the fastest car Chevrolet ever produced. The 2012 ZL1 is currently touted as the highest-performing Camaro in the model’s 45-year history, thanks to its 550HP 6.2-liter supercharged V8 engine, upgraded suspension with Magnetic Ride Control and advanced Brembo brakes. For the moment, Chevrolet has confirmed that it will be offering 500 replicas of the 2011 Camaro SS convertible pace car and the Camaro Synergy V6 variant, the latter aimed at the enthusiasts on a budget. Both are due this spring. It’s also rumored that the Detroit automaker is working on a 2012MY Transformers edition as it’s trying to further capitalize on its involvement in the movie franchise, but there’s no official confirmation on the matter.

Cadillac's All-Wheel Drive Model Sales on the Rise in the U.S.A.

It was a time when associating Cadillac with all-wheel drive was considered to be a heresy. But mentalities have changed and more American customers are specifying their cars with the AWD option. GM’s luxury brand has registered a combined sales increase of 38% for its 4x4 SRX, CTS and Escalade models in the past two years. Specifically, one-third of the SRX crossovers, almost half of the CTS and three-quarters of the Escalade vehicles sold in the U.S. have been equipped with all-wheel drive. Not surprisingly, the highest demand comes from cold weather and mountainous areas. Besides offering better traction on snow, the Cadillac AWD systems also promises to enhance handling and performance in normal weather conditions. According to the Detroit automaker, AWD improves the SRX’s passing acceleration compared to the front-wheel drive version by transferring more torque to the rear wheels, while also reduces the over-steer tendencies manifested by the rear-wheel drive CTS during aggressive cornering. “Cadillac’s investment in advanced AWD systems across the line-up is enhancing the brand’s reputation for performance,” said Don Butler, vice president of Cadillac marketing. “We’re able to offer luxury buyers exceptional ride, handling and control on a wide range of road conditions.” By Csaba Daradics

It Came From eBay Hell: The Geo Storm Pickup You Never Knew You Wanted

Few names in automotive history make the average car enthusiast’s skin crawl like, “Geo”. Geo was General Motors response to the growing number of Japanese and South Korean imports that had invaded the U.S. market. Essentially taking the most boring and insipid models from Suzuki, Toyota and Isuzu and building them stateside, Geo embodied the whole, “Who Gives A...” attitude that has made GM so reviled by some. The Geo Storm was essentially an Isuzu Impulse stripped off all the things that would have made the latter an appealing proposition to the enthusiast: Lotus tuned suspension, turbocharger and AWD. What was left was essentially a four-cylinder sedan with two less doors and a vaguely sporty body. Still, it was a big seller for Geo and GM, no doubt leaving the corpse of Colin Chapman rolling in his grave. And so it was, from the depths of eBay Hell, a “1 of a kind” Geo Storm pickup truck. Behold the myriad of features such as a sliding rear window with “WWII Bomber Girl mural”, gullwing T-Tops and custom 17-inch rims. A fourth generation Camaro-style front end, red white and blue “Patriotic paint theme”, a Chevy Chevelle SS hood cowling and a shaved tail gate handle complete the exterior package. The car retrains Isuzu’s 12-valve engine and 5spd manual transmission, the former of which has recently had a comprehensive tune-up. It’s hard to poke too much fun at the seller: a civilian combat veteran hit by some family health problems. All told it’s a good conversion and the price – US$13,000 – could be a lot worse.
