A revolutionary roadtrain system that would allow cars to “drive themselves” as part of a convoy of vehicles on the motorway is set to undergo testing next year.

The EU project, known as Safe Road Trains for the Environment (Sartre), has been co-ordinated with the help of a UK company to develop technology that will allow a “lead” vehicle, such as a bus or taxi, to assume “normal” driving practice, which the pursuing vehicles will then follow. Once formed, the roadtrains will allow drivers to relax behind the wheel in a similar fashion to current cruise control systems, with a navigation system and a transmitter/receiver taking over driving duties until the driver is ready to leave the motorway.

The system has been designed to increase safety and reduce the environmental impact of motorway driving by exploiting the slipstream that is generated by a convoy of vehicles moving at speed. This passageway of “clean” air reduces the overall drag placed on the car, cutting the amount of fuel used over the course of a long journey.

BMW already is preparing for that launch. Its yearlong trial with the Mini E electric car has opened the auto marketer’s eyes to the maze of regulations facing plug-in electric cars.

“We are learning a heck of a lot just about the sheer infrastructure,” says Jim O’Donnell, CEO of BMW of North America. “When we bring out another electric car, we will be in a great position because we know all the wrinkles.”

BMW has 450 Mini E electric cars running in a yearlong trial in metropolitan New York, New Jersey and Los Angeles. There should be more cars on the roads. But after more than six months of addressing regulatory hurdles, Mini has yet to get approval to install more than 30 additional fast-charge boxes in New Jersey. With a 240-volt box, the Mini E can be recharged in three hours rather than the 21 hours needed using 110-volt power.

“If you are in a house with a normal supply and you want to bring a 240-volt [charger], you have to have an agreement from the power utility,” O’Donnell says. “New Jersey is the most difficult because there are so many local authorities.”

An inspector from each municipality has to approve the installation to make sure it complies with local codes. The cost of the box ranges from $1,500 to $1,800. The box had to be approved by Underwriters Laboratories Inc.

What O’Donnell calls “the New Jersey problem” is compounded because “all the components are certified, but they say the system isn’t certified,” he says. A BMW spokesman says the Mini E experience is a prelude to a more widespread launch of electric vehicles. I just gotta get me one of these beauties, maybe when I retire.

Japan has pretty much been at the forefront of highspeed train technology since highspeed train technology began existing. And thought it’s a bit of a surprise that they don’t hold the current train speed record, I never doubt that they’ve got new train technology around the corner.

So I’m not surprised that Kawasaki Heavy Industries just announced that they’ll be building a new rail line in Japan that will be faster than the previous record holder, the Shikansen.

The new train has a rather lame name “the Environmentally Friendly Super Express Train” but maybe it sounds cooler in Japanese. That is a pretty accurate assessment though. The train’s top speed will be around 217 miles per hour, achieving that speed with less fuel through use of aerodynamics and light-weight materials. Plus, a regenerative braking system will capture kinetic energy in batteries for later use.

Japan has always had a great rail system, but with 10,000 new miles of track planned for the next 20 years, and these new high-speed trains, it seems they’ll just be getting better.
