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.

2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

Why won't automakers slap on a turbo badge anymore?

Where have all the turbos gone? Not the actual pieces that go in the engine, mind you, those are everywhere these days as automakers downsize cylinder counts and boost efficiency and CO2 claims. But the turbo badges and fanfare are missing. Back when turbos were something to get excited about there was "turbo-driven," "turbonium," and "The Turbo Zone," among other silly lines. But now that basically every car is getting some sort of boost even on the lowliest trims, automakers are almost sliding in the turbos under the radar. Or if you look at some of the nomenclature, pretending they don't exist at all. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border. The latest automaker to hide that it has boosted the turbo presence is Porsche with the 2017 911 lineup. Even the standard Carrera models now get turbocharged flat-six engines, meaning the 911 Turbo models aren't quite as special as they once were. Porsche is in a sticky situation with this. The 911 Turbo, after all, signifies where the 911 family takes off from being a sports car and becomes the Ferrari fighter. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border, but now Porsche has crossed it and is trying to downplay the fact. There are a lot of exaggerations with displacement badges today, with claims the 2.0-liter turbo four in a Mercedes C Class equates to a naturally aspirated 3.0-liter six to make a C300. Volvo is pretty far up there, too, saying an XC90 T8 means V8 power, even though it's a 2.0-liter turbocharged and supercharged four with electric assist. I don't know why BMW can't just call the car a 330i Turbo, rather than inflating the numbers up to 340i. Saab tried all of this back in the '90s when it decided to turbocharge its entire lineup, from light pressure units all the way up to models actually called "Saab 9-3 HOT" (for high-output turbo). But then the brand deleted any external reference to the turbo under the hood and people wondered why they were buying a $42,000 four-cylinder convertible. And that didn't turn out well. Even though these turbo replacements often make more power than their naturally aspirated predecessors, they're very different engines. People knew something changed when they exchanged their leased 328i with a 3.0-liter six for a 328i with a 2.0-liter turbo four.
