2015 Mercedes-Benz M-Class to get more fuel efficient engines

Add as a preferred source on Google

Closely following the auto industry’s downsizing trend, Mercedes-Benz is adding two new engines to the M-Class lineup for the 2015 model year.

The first new mill is a 3.0-liter twin-turbocharged V6 unit that sends 329 horsepower and 354 pound-feet of torque to all four wheels via a seven-speed automatic transmission. It returns 18 mpg in the city, 22 on the highway and 20 in a combined cycle thanks in part to a standard start/stop system.

The new V6-powered ML400 replaces the V8-equipped ML550. The 550’s 4.7-liter eight-cylinder engine made 402 horsepower but it returned just 14 mpg in the city and 16 mpg on the highway.

Mercedes hopes a long list of standard equipment will help make up for the loss of power. The ML400 reportedly comes standard with leather upholstery, keyless entry, multi-color ambient lighting, a premium sound system and cup holders that are both cooled and heated. Outside, the ML400 features an AMG appearance package consisting of aerodynamic add-ons as well as 19-inch alloy wheels.

The second new addition to the M lineup is a 2.1-liter four-cylinder diesel engine fed by two turbochargers. Also found under the hood of the E-Class, the GLK-Class and the Sprinter van,  the oil-burner generates 200 horsepower and 369 pound-feet of torque. A start/stop system helps keep fuel economy in check, but Mercedes-Benz has not published official gas mileage figures.

The 2.1-liter-equipped M is christened ML250 BlueTec. It replaces the ML350 BlueTec as the sole diesel-burning ML sold on these shores, and AutoEvolution speculates it will be capable of returning at least 30 mpg on the highway.

The 2015 Mercedes-Benz ML400 will carry a base price of $63,825 when it goes on sale across the nation in the coming weeks. Pricing information for the ML250 BlueTec will be published closer to its on-sale date.

Mazda chief says the MX-5 Miata could go electric
2019 Mazda Mazda3 AWD review

For years, the idea of an electric Mazda MX-5 Miata felt almost impossible. The little roadster has always been celebrated for one thing above everything else: keeping things light. Add a heavy battery pack into the equation, and many enthusiasts assumed the Miata's trademark driving character would disappear along with it.

Mazda, however, appears to have changed its mind. In an interview with German publication auto motor und sport, Mazda CEO Masahiro Moro confirmed that the next-generation MX-5 is being developed with the possibility of an all-electric version in mind. It doesn't mean the iconic roadster is abandoning gasoline anytime soon. Still, it does suggest Mazda wants the Miata to survive in a future where internal combustion engines may no longer be an option.
