Chevrolet looks at optional 50 mpg diesel Cruze.

GM Could be First Domestic Maker to Offer “oil burner” in Compact Passenger Car.

Is a 50 mpg Chevy Cruze diesel in the works?

General Motors appears to be reversing its long-standing resistance to the use of diesel power for its passenger car line-up – and may soon introduce an “oil burner” into its Chevrolet Cruze line-up, which would give the compact model hybrid-level fuel efficiency that could approach 50 mpg.

Like many manufacturers, GM has been wary of diesels despite their chart-topping mileage.  The key issue has been the cost of meeting ever-toughening emissions standards.  But the industry giant has also been concerned whether U.S. motorists would be turned off by diesel’s other disadvantages.

The change in mindset might reflect the continuing growth in demand for diesel-powered offerings now provided by most of the German makers, some Volkswagen, Audi, BMW and Mercedes-Benz models seeing diesel options climbing to nearly a third of their powertrain mix.

While several GM officials declined to comment on the record, they privately confirmed that the high-mileage technology is starting to win converts among senior management, especially with the Obama Administration pushing for fuel economy standards to jump from 37.5 mpg in 2016 to as much as 56.2 mpg in 2025.


Ford Readies All-New Super-Duty Diesel

New design could spawn light truck diesel, but no plans in place.

Ford developed its 2011 Power Stroke diesel in-house and expects "substantial" improvements in horsepower, torque and mileage.

Ford Motor Co. is ready to roll out the first diesel engine it has developed entirely in-house, a quiet, technically-sophisticated and high-mileage “oil-burner” that will replace the old Power Stroke diesel had been outsourcing.

The new 6.7-liter V8 will appear in Ford’s biggest, Super-Duty trucks, models like the F350, where buyers are seeking a mix of stump-pulling torque and high mileage.  But the new diesel could very well be transformed into the fuel-efficient powertrain that many analysts believes the automaker needs in its light-duty F-150, as well.

So Ford officials confirm, but they quickly stress that there are no plans to launch an F-150 diesel, at least not until they can figure out a profitable business equation.



Known internally as Scorpion, the new V-8 is the result of a nearly 4-year development project that was handled much like some of the legendary Skunkworks programs at Lockheed – with developers moving away from the main Ford engineering campus in an effort to minimize the typical bureaucratic interference.
