Xcar rates AWD vs. FWD vs. RWD

With snow and ice blanketing large swathes of the United States over the past few weeks, commuting hasn't been easy. Among some drivers, there's an ongoing debate about how much all-wheel drive really helps when it gets slippery and whether rear-drive is as bad in slick conditions as many people think. Xcar Films puts some of those beliefs to the test in its latest video by showing off three very different cars taking on a trio of low-grip challenges. Xcar's picks for the test include the fairly plebeian, all-wheel drive Subaru Impreza, the somewhat plush, rear-drive BMW 120d and the sporty, front-drive Renault Megane RS 275 Trophy. Things start out easy with a hydraulic plate forcing the back end out on a wet skid pad. From there, the tests get really interesting with a slalom on simulated ice, and the cars finish with a high-speed cornering challenge through a soaked turn. While an obvious winner emerges in the end, keep in mind this is hardly a scientific test of grip. For better accuracy, all three vehicles should be wearing identical tires, and the same driver should be behind the wheel of each one. Still, Xcar's examination is a fun chance to see how vehicles react when things get slick.

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.

First BMW i8 in US sells for $825,000

Here are some numbers. The standard BMW i8 starts at starts at $135,700. The first i8 in the US was auctioned off at the Pebble Beach Concours d'Elegance this past weekend and the auctioneers, Gooding & Company, said before the gavel was lifted the fist time that they expected the i8 with unique Frozen Grey Metallic and other upgrades to raise between $150,000 and $200,000 for the Pebble Beach Company Foundation. Turns out, the car eventually sold for $825,000 to an unnamed buyer. Along with the honor of having the first i8 on these shores, the special plug-in hybrid comes with Dalbergia Brown leather upholstery, a set of Louis Vuitton luggage and something called a "professional edition" charging station along with laser headlights (subject to regulator approval). A number of other i8s were delivered to a few wealthy car shoppers who managed to make their way to Pebble Beach over the weekend, including automotive guru Roger Penske and Nest CEO Tony Fadell. The special edition was presented at the auction by Jay Leno and BMW North America president and CEO, Ludwig Willisch. You can't put a price on that. Just kidding. You can, and it's apparently $825,000.
