Voltec 5ET50 Drive Unit Is Lighter, Smaller And More Powerful

Two GM engineers tell us about the all-new powertrain in the 2016 Chevy Volt and why it is so much better than the one in the first-gen model.

'XL' often means "bigger," but a new powertrain from Massachusetts-based startup XL Hybrids actually shrinks your fuel budget. About 21 percent smaller, to be precise.

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. The plants will use the funds build a new Ecotec small gasoline engine as well as a new V6 and eight-speed automatic transmission. The cash will also go towards retooling a current six-speed transmissions. Flint will receive the b

In addition to confirming the upcoming Kansas City-built Transit van, a recent UAW release states that Ford will be adding an "industry-leading small V6" to its powertrain lineup. Car and Driver reports that, while the automaker has yet to confirm the development of such an engine, Ford stated that adding a smaller-displacement V6 would make sense based on its current powertrain strategy.

What is it with companies thinking they can get around the Clean Air Act? Earlier this year, the second-largest refinery in the U.S. was fined $5.3 million (and required to upgrade pollution control systems for $700 million) for CAA violations. Before that, companies like Pep Boys, Cummins and Mercedes (among others) were all forced to pay fines for selling products that are just plain dirtier than they should be.

Does the gas station pump pictured above look confusing? For some people, it is. Now, imaging if there was also J1772 connectors and a few H2 pumps, a SVO hose, and one for biodiesel and E85. Would it be complicated then? According to a new online study by Harris Interactive (done at the behest of Mercedes-Benz USA), these sorts of choices – more specifically, the new generation of alternative powertrain vehicles – are causing confusion about what kinds of cars to buy, with the resul

When the 2011 Honda CR-Z hits the streets this Fall, it will feature the latest iteration of the company's Integrated Motor Assist (IMA) mild hybrid system. The basic concept of IMA hasn't changed since the original Insight debuted in 1999, but it has been refined to improve performance and efficiency while reducing overall cost.

There have been periodic rumors of a United States assembly plant for Volvo cars since at least the early 1980s. There was a North American construction arm of the Swedish carmaker, situated in Nova Scotia, but that plant has been shuttered for several years now. Volvo CEO Fredrik Arp has told Automotive News that an American plant would take an unacceptably long time to pay for itself, according to the automaker's studies. A weak dollar doesn't help the economic argument for a plant in the Sta

Hyundai has just announced a new Certified Pre-Owned Limited Warranty on used (sorry, "previously owned") vehicles that are up to five years old and have less than 60,000 miles. Known for being the first to offer a 10-year/100,00 mile powertrain warranty on its new cars, Hyundai will now be including that same lengthy coverage with the purchase of a CPOV.

General Motors dropped a bomb this week when it announced that it was upping its powertrain warranty coverage to 5 years/100,000 miles. That gives the General the best warranty coverage of any full-line automaker, but which company has the best overall warranty coverage and which the worst? Where does your favorite brand fall in the mix? Cars!Cars!Cars! did some digging and compiled a complete list of every automaker's warranty coverage. It's great to see this information compiled in one place,
