BMW M4 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.

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 X4 M40i leaks ahead of LA Auto Show

Leaked photos of the higher-performance BMW X4 M40i emerged today ahead of its expected debut at the 2015 LA Auto Show. The new model builds on the xDrive35i model, offering an extra 60 horsepower and 43 pound-feet of torque. The hotted-up X4 should use that power well. According to Auto Guide, it will hit 62 miles per hour in 4.9 seconds and should be limited to a top speed of 155 mph – a notable improvement over the existing xDrive35i, which takes 5.2 seconds to hit 60 and has a top speed of 130 mph. Expect the X4 M40i to be followed by an similar version using the X3's more versatile body style, both of which will use an eight-speed automatic and a more aggressive all-wheel-drive setup. Despite the "M" in its name, this is not a full-blown M car. Instead, it takes the same tack BMW has used for the M235i here in America, as well as the M50d models sold in Europe: higher performance over stock, without offering the full enchilada that is a proper M car. That explains the slightly more aggressive body kit, which isn't as sporting as that of a proper M car. On top of the new front and rear clips, there's a set of meaty 19-inch wheels that look to be wrapped in sporty Michelin Pilot Super Sport tires. In the cabin, an oversized M-branded steering wheel is the most notable addition. Naturally, we'll have the full range of details on the X4 M40i when it debuts in a couple of months in LA.
