BMW i8 pitted against M4 in sibling rivalry track battle

We recently watched Auto Bild challenge the BMW i8 against the M4 in a German drag race of decide the quicker of the inter-brand rivals. The hybrid took a commanding victory in that fight. However, Autocar now has a new battle for the two coupes. The siblings are together again on the Castle Combe Circuit to find out which of them offers the more enjoyable experience at the track. Unfortunately, we don't ever get a perfect point of comparison in the video because host Steve Sutcliffe never does a full lap in anger with either of them to set a time. Instead, he focuses more on how the BMWs feel behind the wheel. Sutcliffe also admits midway through the clip that the i8's electric motor is out of juice to power the front axle's electric motor. That only leaves the hybrid with its 228-horsepower and 236-pound-feet-of-torque turbocharged three-cylinder to spin the rear wheels. Still, Sutcliffe spends ample time explaining the benefits and downfalls of driving these coupes. See where his opinion falls between the M4 as the traditional German sports coupe and the i8 as the new-school hybrid in the video, above.

BMW M4 Concept leaked ahead of Monterey debut

Last month, we heard that BMW might be bringing a concept previewing its next M4 sports coupe to this year's Monterey festivities. Well, thanks to the folks at USA Today, we have absolute confirmation of this by way of some leaked images. And goodness, she's certainly a looker.
While a few of us still find some of the 4 Series' design to be a bit awkward, it's hard to not immediately warm up to the aggressive bits of this hotter M4 concept. It certainly looks the business of a proper sports car, and a worthy successor to the M3 coupe. Of course, a lot of this will likely be toned down for the production version, which we'll likely be seeing at the 2014 Detroit Auto Show in January, along with its four-door M3 kin.
The official M4 Concept details will be revealed later tonight, but for now, have a look at a few shots of the golden show car in our gallery of leaked shots, above.

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.
