GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

Four recreational vehicle companies in Texas have settled with the EPA over illegal import and sale of off-road vehicles. The 4,000-plus Hammerhead brand vehicles in question were imported without the proper certification, a violation of the Clean Air Act. Some vehicles lacked proper emission control equipment or were manufactured by a company not listed on the certificate application. The settlement totals $560,000 in civil penalties for the companies involved. Read more from the EPA. The Iowa Supreme Court has upheld the state's natural gas tax, which was challenged by the ethanol industry. Ethanol producers, which use natural gas to make ethanol, argued the complicated tax was unconstitutional, as it forced certain plants to pay more than their competitors. Taxes vary by location, and some plants have to tap into interstate pipelines at much higher tax rates rather than get it from a local utility. Now, ethanol producers will work to change the law. "My hope is that people understand that, something may be constitutional but that doesn't make it good public policy," says Iowa Renewable Fuels Association Executive Director Monte Shaw.

Valeo says Audi will launch a vehicle using its electric supercharger next year, with other reports suggesting that car will be the Audi Q7. The company says other unspecified automakers will also use the technology in their vehicles. While the electric supercharger adds to the vehicle's cost and electric energy use, it can improve fuel economy by as much as 20 percent. Read more at Automotive News Europe.

Chevy to resume engine-building program for 2015 Corvette Z06

One of Chevrolet's most popular and unique customer features is set to return for 2015, as the company has announced that the Engine Build Experience is back. Interested owners will be able to screw together their engines beginning in March. The $5,000 option (which does not include the cost of travel) will give future owners of the 2015 Corvette Z06 the chance to screw together their car's actual 6.2-liter, supercharged V8. Available on each of the Z06's three trims, the Engine Build Experience includes a day at the Performance Build Center, instruction from an engine assembly tech, photographs of the experience and a personalized engine plaque. Once the build process is completed, the engine will (eventually) be fitted under the hood of the customer's personal Z06. "Chevrolet recognizes the passion customers have for Corvette and the Engine Build Experience offers them a truly unique opportunity for hands-on involvement in the creation of the heart of their new car," Corvette product manager Harlan Charles. "It's important for customers to understand their engine won't be installed the day after they built it. It will flow into the scheduling process for vehicle assembly, which depends on a number of logistical variables." Scroll down for the official announcement of the Z06's Engine Build Experience, available below.
