Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises. You can check out the full press release below. You can also read the full study on the Consumer Reports site, or scroll down for a short video recap.

BMW i8 pitted against M4 in sibling rivalry track battle

We recently watched Auto Bild challenge the BMW i8 against the M4 in a German drag race of decide the quicker of the inter-brand rivals. The hybrid took a commanding victory in that fight. However, Autocar now has a new battle for the two coupes. The siblings are together again on the Castle Combe Circuit to find out which of them offers the more enjoyable experience at the track. Unfortunately, we don't ever get a perfect point of comparison in the video because host Steve Sutcliffe never does a full lap in anger with either of them to set a time. Instead, he focuses more on how the BMWs feel behind the wheel. Sutcliffe also admits midway through the clip that the i8's electric motor is out of juice to power the front axle's electric motor. That only leaves the hybrid with its 228-horsepower and 236-pound-feet-of-torque turbocharged three-cylinder to spin the rear wheels. Still, Sutcliffe spends ample time explaining the benefits and downfalls of driving these coupes. See where his opinion falls between the M4 as the traditional German sports coupe and the i8 as the new-school hybrid in the video, above.

More details emerge on hotter BMW i8S coming next year

The BMW i8 recently won the Autoblog Technology of the Year award, and it's going to get even better. In October, Automobile magazine reported that BMW's i brand is working on an i8S that would be stiffer and more powerful, and celebrate the marque's centenary in 2016. At the time, one of two power unit combinations was suggested, either one of them good for more than 500 horsepower. Car magazine has added more info on the coupe said to be called Project M100, saying that in addition to being a birthday gift for BMW, it will also be a going-away statement to current chairman Norbert Reithofer, who is expected to retire in 2016 or 2017. It will also be so thoroughly reworked that there will be plenty of daylight between it and the standard i8: a more integrated carbon fiber and aluminum chassis, a wider range of materials used in the build, a larger luggage bay due to the omission of rear seats, a more aggressive suspension supporting heartier brakes and wider tires, and - perhaps - a different aero and ground-effects package to be visually different and make the most of the alterations. As for that power unit, Car says that the two options mentioned by Automobile are still under consideration, being either a 2.0-liter twin-turbo four-cylinder with 320 horsepower and a 204-hp electric motor, or a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Either choice gets an integrated starter motor good for another 27 hp, and a total torque number of roughly 520 pound-feet, 100 additional lb-ft than the current car. Word is that it will be shown for the centenary in 2016 then go on sale by the end of 2017.
