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 looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

2015 BMW X4 slides in on the diagonal starting at $45,625 in the US

If BMW has shown us anything, it's a knack for creating niches and expanding its product portfolio. Go back to the early '90s and it had essentially four models: the 3 Series, 5 Series, 6 Series and 7 Series. End of list. Since then, the Bavarian automaker has not only taken on Mini and Rolls-Royce, but has expanded its own range of models exponentially. You can chalk a big part of that up to crossovers, and another sizable chunk to giving existing models a different roofline and calling it something new. What we have here is a prime example of both.
Previewed in concept form the better part of a year ago at the Shanghai Motor Show, the slantback version of the X3 (and the baby brother to the X6) is now here in full production guise. Mechanically it's essentially the same as the new X3 on which it's based, but amps up the "sport" at the expense of the "utility" part of the SUV equation.
BMW will undoubtedly offer a wide range of powertrain configurations in markets around the world, but back in the United States it'll be offered in two specs: the X4 xDrive28i, packing a 2.0-liter inline-four with 240 horsepower and a $45,625 sticker price (including destination), or the X4 xDrive35i with the 300hp 3.0-liter six and a $48,925 MSRP. Either way, you're getting an eight-speed automatic and all-wheel drive.
