•Decoupled loads: generator works to charge batteries, while batteries provide power to turn the wheels.
•Open generator architecture: the Wrightspeed Route ™ can use any number of on-board power generation options, including micro-turbines and piston engines.
•No range anxiety! The Route ™, given refueling, has an unlimited range
High-Power Battery System
•Exceptional regen capability: 400 hp
•The high-power battery system provides peak power, allowing the generator to operate at its most efficient point.
•PLUG IT IN, for up to 40 miles on grid energy.
That's good that it can plug in, but it begs the question: If you actually believe the claim that it's cleaner to run it off the turbine then why would you plug it in? Of course in practice I'm sure it'll come down not to what's cleaner, but what's cheaper.edatoakrun wrote:PLUG IT IN, for up to 40 miles on grid energy
Mazda will unveil a new rotary-powered sports car concept at the 2015 Tokyo Motor Show later this month.
The concept should prove popular with fans of the brand, who have bemoaned the lack of a rotary-engined sports car since the RX-8 departed in 2012.
But this concept could also have implications for those who prioritize fuel efficiency over performance.
... just a few years ago, there was chatter about Mazda using these engines as range extenders in future plug-in cars.
In 2013, we saw a range-extended electric Mazda 2 prototype that used a small rotary engine to charge a battery pack.
The car used a front-mounted, 100-horsepower electric motor for propulsion.
But it also had a tiny 330-cc rotary engine mounted under its rear cargo deck--capable of increasing range to 300 miles on the Japanese testing cycle.
The setup was similar in concept to what is currently used in the BMW i3 REx. The engine's tiny gas tank meant it was only a supplementary power source...
Overview: Nissan Exhibit at 2015 Tokyo Motor Show
...The Nissan Gripz Concept, conceived by designers in Europe and Japan, aims to blend the ability and practicality of a compact crossover with the excitement and performance of a sports car.
Equipped with an EV-technology-based series hybrid system—Pure Drive e-Power—, the Nissan Gripz Concept delivers a smooth, refined and exhilarating driving experience with outstanding fuel efficiency. Within the system, an efficient gasoline engine powers the same electric motor used in the Nissan Leaf...
Nissan EV range extender in 2016
...To be revealed in 2016, the new vehicle will be self-proclaimed EV market leader Nissan’s first attempt at offering an electric car with a small combustion engine. Unlike regular and plug-in hybrids, the (usually tiny) engines have no connection to the driving wheels.
...Yoshi Shimoida, Nissan’s Deputy General Manager, EV and HEV engineering division, revealed to motoring.com.au that there will be “no engine” for the LEAF in future, ruling out the world’s best-selling EV as a donor car.
“But in the future Nissan will add [a new vehicle] to the line-up of EV systems an engine that is only for generating energy,” said the EV technology specialist....
The Japanese EV guru wouldn’t be drawn on the Nissan EV’s range...
Shimoida wouldn’t say what the new vehicle will be called although he did reveal it’s going to be announced sooner rather than later.
“Next year we announce what it’s called,” he stated.
If the new vehicle is not going to be a LEAF, it’s possible an all-new vehicle premiering the range-extending EV technology for Nissan could be introduced...

You could compare the range extender to any portion of your battery that gives you range greater than your average drive. In the Volt's case the 53 mile range of the battery is good for about 90% of most peoples driving needs. For that last 10%, you need the range extender. In the case of the Bolt everything about the battery that is needed to go beyond that can be compared to the Volt range extension hardware. I don't know the numbers but it would be interesting to compare weight, volume and cost of a range extender against simply putting in a larger battery.
