BMW M4 to debut in Detroit, lose manual transmission

BMW took the wraps off its M4 Concept at Pebble Beach last weekend, and many speculated that the highly anticipated production version of the sleek new two-door sports coupe would debut at the Los Angeles Auto Show later this year. But a well-placed source tell Autoblog that the E92 M3's successor won't arrive in Southern California this November. Instead, the German automaker will wait until the Detroit Auto Show in January for its first official reveal.
An all-new 3.0-liter inline-six with twin turbochargers is expected under the hood, and it should provide about the same horsepower as the current 4.0-liter V8 (rated at 414 horsepower), but with much more torque that arrives lower on the tachometer. The lightweight engine is said to have an impressively high redline, which is unusual for a turbocharged engine.
Unfortunately, Save the Manuals members aren't going to like this next bit of news. After four generations of three-pedal M3 models, our source says the upcoming F82 M4 will arrive with a dual-clutch transmission (DCT) as standard equipment - with no manual option - just like the latest iteration of the track-ready Porsche GT3 (few have complained about the automaker's PDK after driving the latest sports car from Stuttgart). In exchange for some moans, groans and gripes from enthusiasts, BMW's DCT mounted aft of the M4's inline-six will provide quicker acceleration and improved fuel economy.

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.

Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.
