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:

Hydrogen stations that don't work putting a dent in H2 lifestyle

Hydrogen is the most plentiful element in the universe, but it's not abundant enough for some hydrogen fuel-cell vehicle drivers. Southern California lessees of models such as the Hyundai Tucson Fuel Cell SUV are taking to Facebook to voice their complaints about out-of-order fuel cell stations, Green Car Reports says. In many cases, the lack of hydrogen supply has made the cars effectively undriveable. For Tucson Fuel Cell owners, the hydrogen is supposed to be free and unlimited, but Hyundai doesn't manage the stations. One Orange County lessee of a Tucson fuel-cell vehicle hasn't driven the car for over a month because the trio of nearby stations are out of commission. Additionally, some of the stations that do work can only provide about a half-tank worth of hydrogen, once again putting a crimp the driving range of the hydrogen car. California is home to 10 of the dozen public hydrogen refueling stations in the country (there's one each in Connecticut and South Carolina), according to US Department of Energy figures. These sorts of challenges can't help Hyundai's hydrogen efforts. Last month, it was reported that Hyundai has sold fewer than 300 fuel cell vehicles worldwide during the past three years, including about 70 through the first five months of this year. The South Korea-based automaker has said it wants to sell 1,000 fuel-cell vehicles globally by the end of 2015. Fuel-cell drivers and advocates alike are hoping that Toyota will change the game when its Mirai hydrogen vehicles start hitting California roads later this year. Toyota confirmed in May that Mirai US sales would start in October in eight California dealerships. The Northeast is on tap for 2016. Related Video:

Weekly Recap: Toyota wants cars to be your 'close friends' around 2020

Toyota confirmed plans this week to launch autonomous technology in its production cars around 2020. The automaker's version is called Highway Teammate, and it's one element of a broader mobility strategy that includes vehicles communicating with each other and the grid. "Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out," the company said in a statement. That sounds utopian, and perhaps a bit cheesy, but it's an acknowledgment that autonomous driving requires more than technology developed in a vacuum. Toyota is looking at its research in a broader context, and dubs its overall strategy the Mobility Teammate Concept. Highway Teammate is the first step. Its test vehicle is a modified Lexus GS, which uses road-mapping data and external sensors to merge or exit highways, change lanes, and maintain safe distances during driving. It's operated on the Shuto Expressway in Tokyo. Toyota has been working on autonomous tech since the 1990s, with the goal of providing mobility for older people and the disabled, as well as lowering the frequency of traffic accidents. Toyota's push comes as an early adopter, Nissan, is hedging on its own deadline to implement the autonomous tech by 2020 due to a lack of firm laws governing self-driving cars around the world. Conversely, Volvo took the landmark step of being the first automaker to accept liability for when its cars will operate in autonomous mode, and urged the US government to set federal guidelines to regulate the technology. OTHER NEWS & NOTES 2016 BMW M4 GTS: Your water-injected, turbo-boosted demon BMW is unleashing its most powerful M4 ever, a 493-horsepower special edition that's road legal yet bred for the track. The company is making 700 copies for sale around the world, and 300 of them will come to the United States. The twin-turbocharged 3.0-liter six-cylinder revs to 7,600 rpm and uses a water-injection technology to cool the intake air and lower the compression temperature. BMW says this allows it to wring more power out of the inline six. The car also uses carbon-fiber reinforced plastic for the roof, hood, engine compartment strut brace, drive shaft, and rear spoiler to reduce weight. The M4 features BMW's organic light-emitting diode taillights, which are said to be an industry first.
