It's a good week for the town of Spring Hill, TN, as General Motors has announced that its factory in the city of 31,000 will receive a $185 million contract to produce engines. On top of that, the next-generation Cadillac SRX crossover will be built at the factory (NA models are presently built in Ramos, Arizpe Mexico), which was once famous for being the home of GM's now-defunct Saturn brand.

But Chevy Discontinuing More Efficient Mild-Hybrid eAssist Model

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined.

General Motors has announced it will invest around $332 million to produce more fuel-efficient engines and transmissions. The cash will be split between four manufacturing facilities, including Bedford, Indiana and Toledo, Ohio, as well as Bay City and Flint, Michigan.

Chevrolet won't sell the Cruze wagon or the Cruze hatchback here in the U.S., and dammit if that doesn't make us angry. Now Australian tuner Walkinshaw Performance is adding insult to injury with this hotted-up Holden version of the Cruze.

The EPA has delivered the fuel economy results for the 2013 Cadillac ATS with the 2.5-liter, four cylinder: 22 city, 33 highway, 26 combined. The response so far range from 'That's not what we expected' to 'Well, what did you expect?' Cadillac describes the ATS as a "compact luxury sedan... built on a foundation of quick, nimble fun-to-drive dynamics and mass efficiency," so everyone is ready to grade on the sports-sedan curve, and while we think taken on their own they're fine if nothing specia

Rumor has it that if you give Canadian engine tuner Nicolas Brunet a 2.0-liter, turbocharged General Motors Ecotec motor, he'll make it capable of breaking the quarter-mile record for four-cylinder dragsters. We say "rumor" because this news apparently hasn't been independently confirmed yet, but at Napierville Dragway in Quebec, Canada, the funny car you see above ran 6.75 at 206 mph.

While the investigation of the Fisker Karma that toasted a Texas garage is not over, pundits have begun to weigh in. Automotive News has found a particularly credible one in Jon Bereisa, CEO of Auto Lectrification and the chief engineer of the General Motors EV1 and systems architect for the Chevrolet Volt. And according to Bereisa, the poor packaging of the Karma's internal combustion engine is what likely caused the fire.

General Motors announced today that it would be overhauling its smallest engines, replacing three engine families with a new, modular Ecotec design. Production of new three- and four-cylinder powerplants should begin mid-decade, ramping up to over two million engines a year by 2020.

It matters not whether you want to chalk it up to rising fuel prices or a gradual change in vehicle buying preferences, the reality is that the American public keeps snatching up fuel-efficient vehicles powered by four-cylinder engines. Of course, soaring demand for four-cylinder-engined vehicles means that automakers must pump up output of the once-lowly four-bangers. General Motors is doing exactly that.

General Motors has announced that it will invest $109 million to boost production of its 1.4-liter four-cylinder Ecotec engine. GM says this spending will add (or keep) 96 jobs at its manufacturing facilities in Flint, MI and Bay City, MI. Of the $109 million, $84 million will be used to increase engine production capacity in Flint. Bay City's investment of $25 million will go towards boosting output of connecting rods and camshafts used in the 1.4-liter mill.

General Motors has announced that it will invest a total of $483 million in its Spring Hill, Tennessee powertrain facility by 2012. The news comes as GM continues to move toward building more fuel-efficient engines. The automaker says that the next-generation Ecotec four-cylinder engine, complete with direct-injection, will be built in the Spring Hill plant. Those funds will also go toward bringing back a total of 483 workers that have been idle since last year.

In the automotive realm, marketing can sometimes prove just as important as the actual product. Take, for instance, Ford's well-regarded EcoBoost technology, which couples turbocharging with direct injection to produce more horsepower and reduce fuel consumption. Would it surprise you to hear that General Motors has had similar technology on the market for over three years?

Building cars is expensive, and many of the priciest bits of technology driving research and development costs are wrapped up in the powertrain. Therefore it's not particularly surprising to hear that General Motors has just announced a $494 million investment to build the next generation of Ecotec engines.
