Top Gear drag races the BMW i8 and M4 to decide the future

The BMW M4 and i8 represent two every different expressions of the performance car. The M4 relies on its turbocharged six-cylinder combustion engine to spin the rear wheels. Conversely, the i8 packs a turbo three-cylinder and electric motors for its cutting-edge all-wheel drive system. Top Gear is the latest publication to put the pair together to find out which ethos is quicker. We saw Germany's Auto Bild hold a similar race last year, and the i8 scored a clear victory there. We don't want to spoil the winner of Top Gear's attempt, but we can tease that this sprint ends in a photo finish. Pick your favorite, and then watch the video to see which performance coupe takes the checkered flag. Related Video:

LA Design Challenge invokes biology for 2025 concepts [w/poll]

Participants in the annual LA Design Challenge always manage to come up with edgy, wacky designs for future vehicles, but with a theme of "Biomimicry and Mobility: 2025" this year's crop of cars might be the quirkiest we've ever seen. As usual, automotive designers from around the world participated in this year's competition, and all the designs will all be unveiled next week during the LA Auto Show with a winner being announced on November 21.
Chinese automakers made a strong showing with Qoros, SAIC Motor, JAC Motors (the company responsible for the Ford F-150 clone) and Changfeng all bringing interesting takes on the biology, human intelligence and sustainability theme. One of the more innovative ideas among these automakers is the Qoros Silk Road System allows autonomous vehicles to drive in packs similar to how ants travel. Speaking of ants, the SAIC Motor Mobiliant (shown above) gets its design from the shape of an ant's body, and, like the insect, it can climb building acting as a personal elevator as well. The JAC Motors design also merges vehicle and building design, while the Changfeng LaBrea inspired by the design of muscle fibers.
Other entrants include Subaru and US-based design teams for BMW, Toyota and Mazda. BMW's duo of concepts mimic plant and animal life. The LA Subways concept acts as a submersible, single-person vehicle to take advantage of the LA river, with a shape similar to an Ocean Sunfish. The Sustainable Efficient Exploratory Device (SEED) imitates the shape of a seed pod, and uses propulsion methods inspired by a shark, dragonfly and a water bug. Mazda's Auto Adapt might be the most car-like concept of the bunch, while the Subaru Suba-Roo and the Calty-designed, Toyota e-grus are the most mind-blowingly awesome.

BMW i8 Spyder production could still be years away

BMW will still build a convertible version of the i8, but production of the droptop hybrid sports car won't happen for at least a couple more years. That's according to an anonymous BMW insider speaking to Motoring. "There will be no new i models in 2016. Not even the convertible," the insider told the Australian publication. While the i8 Spyder might not arrive for a while, the company still sees a place for it in the model range. "The i8 is selling well enough now, so the lineup doesn't strictly need it," another unnamed BMW insider told Motoring. "We are doing it, we are just doing it slowly because it's not all we are doing." The automaker sold 2,265 examples of the i8 in the US in 2015, which was up from 555 in 2014. BMW first imagined the convertible i8 with the Spyder concept way back in 2012, and a report in 2013 hinted that it was near production, which never happened. The company then sliced off the sports car's doors and roof for the orange I Vision Future (pictured above) at the recent 2016 Consumer Electronics Show. The concept's open design gave BMW an easy place to show off the AirTouch gesture control system at the tech event. These insider claims are a complete reversal from BMW CEO Harald Kruger's assertion in December that the company would soon unveil the production i8 Spyder. The boss didn't indicate the debut's exact timing, but it seemed a lot sooner than at least a year from now. We'll have to wait and see. Related Video:
