  • 2018 BMW M4

    The BMW M3 and M3 are about to become a little less special as both the sport sedan and coupe will switch from carbon fiber-reinforced plastic (CFRP) driveshafts to fairly commonplace steel components. BMW says the reason behind the switch involves emission standards and future compliance. The CFRP driveshafts are wider than steel units and take up more space under the car. BMW plans to add a particulate filter to the exhaust system in the near future and the CFRP driveshafts simply don't mesh with the emissions equipment. However, BMW assures enthusiasts that the steel units have been...

  • McLaren MP4-12C supercar

    It's no secret that getting a lot of power out of a small package is a solid recipe for efficiency--just as Honda about four-cylinders, or BMW about inline sixes--but a 600-horsepower supercar being more efficient than a hybrid? That's got to be a special case, right? Well, yes and no. The very small (for a V-8) 3.8-liter twin-turbo in the McLaren MP4-12C isn't going to win any hypermiling competitions, but it does create less tailpipe emissions than most hybrids, per horsepower of output, according to its creators. Come again? That is, if McLaren meets its goals in efficiency and power for...
