Reuters: Tesla looking to start testing autonomous semi in “platoon” formation

Tesla CEO Elon Musk announced in April that the company is working on pushing a long-haul electric semi truck to market, which is set to be formally revealed in September. Now, Reuters has viewed e-mail correspondence between Tesla and the Nevada Department of Motor Vehicles that indicate that the company has discussed testing semi trucks on the state’s roads.

The Reuters report also mentioned that the semis would be outfitted with autonomous functions, so they could traverse the nation’s highways without a driver in the front seat. The e-mails seemed to indicate that Tesla’s semis would “platoon,” that is, drive in a formation such that a number of trucks could follow a lead vehicle. It’s unclear whether the lead vehicle would have a driver, or operate autonomously with a person in the front seat to monitor safety.

The idea of “platooning” autonomous semis is an old one. More than a year ago, the Dutch Ministry of Infrastructure and the Environment held an autonomous truck platooning demo that involved automakers such as DAF Trucks, Daimler, IVECO, MAN, Scania, and Volvo. The advantages of platooning is that it’s theoretically safer—if the lead truck slows down, the rest automatically follow. It also offers most of the trucks decreased wind resistance, which could help increase an EV semi’s range—a major concern given the weight freight companies load semis with. Of course, there are social ramifications too. Platooning reduces the number of drivers that a shipping company would have to employ.

BMW boosts i3 battery capacity by 50 percent—and it’s retrofitable

May 2nd, 2016

When we reviewed the BMW i3 back in 2014, the little rear-wheel drive city car left us quite impressed. However, the i3 has always had a couple of flaws in comparison with other electric vehicles out there; it costs too much and the range isn’t very good, even if you go for the optional two-cylinder range-extending engine. It appears BMW has decided to address the latter issue, because from this summer the i3 will now come with a 33kWh battery in place of the current 22kWh unit.

Battery technology—and the amount of kilowatt-hours a dollar buys—keeps getting better each year. Certainly it improves measurably over the lifespan of a car, and the fact that BMW has seen this and bumped the battery spec for the i3 is a promising sign for the industry. That probably sounds like we’re damning with faint praise, but technology now moves too rapidly for OEMs to stick their old cycles of refreshing cars every four years. If BMW wants to sell any i3s once the Chevy Bolt and Tesla Model 3 start shipping, a range boost is the bare minimum it needs to do.

The new battery is 50 percent bigger, so more than 100 miles (160km) should be possible on a full charge. The gas tank for the range extender engine will also grow by 25 percent; expect to stop for gas every 75 miles if you try road-tripping. These range tweaks should help boost the i3’s appeal, but before long the Bolt and Model 3 are going to make people expect 200+ miles from their EV as a bare minimum.
