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.

BMW 5 Series Gran Turismo won't be a one-and-done model

The BMW 5 Series Gran Turismo seems like a model without a real segment to fit into. It doesn't quite match the mold for the swoopy four-door coupe niche like the Porsche Panamera or the brand's own 6 Series Gran Coupe. However, the vehicle isn't really a station wagon to appeal to those utilitarian buyers, either. Despite this identity crisis, BMW is reportedly prepping another GT for the next-gen 5 Series platform. According to German magazine Auto Motor und Sport, the 5 Series GT somehow has been a big enough sales success in the US and China to warrant another model. The next one would allegedly arrive in 2016, which is the about the same size as the future 5 Series sedan. The magazine speculates the new GT could lose about 221 pounds in the transition and be offered with four- and six-cylinder powertrains, plus a plug-in hybrid with an electric driving range estimated at around 19 miles. Globally, China is actually the larger 5er GT market than the US. According to IHS senior analyst Stephanie Brinley to Autoblog, the variant sold 21,089 units worldwide in 2013 (2014 is still being tabulated), and that represented about 5.7 percent of the 370,930 total sales for the 5 Series. China bought 42 percent of the world's GTs, compared to about 10 percent of the mix from the US. Europe, meanwhile, took about 29 percent of them that year. While the GT's sales figures make up just a fraction of the overall 5 Series, the variant is still a moneymaker for BMW, and IHS forecasts a second generation, too. "The 5 Series range as a whole is stronger for having this product, and it's very likely that the company's profit margin is higher on the GT, even with the cost of some dedicated sheetmetal and tooling," said Brinley.

BMW 4 Series spied with its future competition

BMW showed off its new 4 Series coupe in concept form at the 2013 Detroit Auto Show earlier this year, but it won't be long before we see the production model, evidenced by this modestly camouflaged prototype spotted testing. In case you forgot, the 4 Series serves as the replacement for the two-door versions of the BMW 3 Series, just as the upcoming 2 Series will effectively be the new version of the 1 Series coupe and convertible sold in our market.
This isn't our first glimpse of the 4 Series out testing, and we've even spied its droptop, Gran Coupe and too-hot M4 kin. We don't expect the final design to stray too much from the concept car seen in Detroit, albeit without the normal conceptual goodies like oversized wheels and with the overstyled front fascia toned down a bit. Our spy photographers even caught the 4 Series coupe hanging out with an Audi A5, giving us a good glimpse at how the two cars will stack up in terms of size and design.
It's still unknown exactly what engines will power the car when it comes to production, but since this thing is a derivative of the 3 Series, we expect the usual range of turbocharged four- and six-cylinder engines to be available, likely in 428i ad 435i guise (though, to be fair, the larger 640i coupe uses a 3.0-liter turbo engine, so there's even the potential for 440i nomenclature to work its way into the mix). We'll have to wait until the car officially bows later this year to know for sure.
