BMW offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:

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.

The 2017 Alpina B7 xDrive isn't as cool as the BMW M760i

Steve Ewing is good people, but when it comes to big BMWs, he talks nonsense. He argues, incorrectly, that the new Alpina B7 is somehow cooler than the new M760i. Here's why he's wrong. No surprise, but the bulk of the pro-M760i argument comes from under the hood. Yes, both cars produce 600 horsepower and 590 pound-feet of torque, but it's where the power comes from that really matters. The M760i's power is just much more accessible, with peak torque coming in at just 1,500 rpm, while the Alpina makes owners wait until 3,000 rpm for max twist (a fact Ewing glosses over). The V12 also offers up all 600 horsepower at 5,500 rpm, 250 rpm earlier. Sure, the Alpina is 0.3 seconds faster to 60 miles per hour – it does the deed in 3.6 seconds to the M760's 3.9 seconds – but it relies on a tweaked transmission setup to do it. Not only that, but big automakers like BMW are usually quite conservative about performance figures, so it's still a bit early to hand a medal to the aftermarket. Here's the other thing about the engines – Nigel Tufnel would prefer the M760i. See, the Alpina has a 4.4-liter, twin-turbo V8, but the M760i has a 6.6-liter, twin-turbo V12. To paraphrase Tufnel, "This one has a V12." We rest our case. Other changes between the two cars are largely in the eye of the beholder – we can talk about the transmission, suspension, and xDrive changes until we're blue in the face, but we simply don't have enough information about the two setups to make substantive arguments – some people might prefer the subtler styling of the M760i. We're not going to blame anyone for liking the more aggressive look of the Alpina, with its big, quad-tipped exhaust, meaty front splitter, or aggressive side sills. And those 21-inch Alpina wheels? Easily the coolest styling detail. You can get a closer look at them, and the Alpina's other changes, in our live gallery from the floor of the Geneva Motor Show.
