Clever Structural Engineering for EV Motorcycle
Electric vehicle batteries tend to be comparatively heavy and when you’re developing a high-performance café racer, the objective is to make it as light as possible. So Arc, a U.K.-based company that is developing the Vector racer, which has a 399-volt battery that produces 133 bhp and 109 lb-ft of torque, a top speed of 125 mph and a 0 to 60 mph time of three seconds, has done something rather clever: It is using a carbon-fiber monocoque that houses 960 Samsung 21-700 lithium-ion batteries and the motor so that it is both light and structurally stiff.
The Vector has a mass (dry weight) of just 492.6 pounds.
Arc has tapped a number of well-known suppliers for components for the bike that is going to go into production next year at a facility in South Wales. Continental provides the anti-lock brakes, Brembo the brake discs, Ohlins the suspension, Pirelli the tires, and so on.
The bike is estimated to have an urban/ex-urban combined range of 270 miles.
The company anticipates that when the Vector goes into production 399 will be built to order in the first 18 months.
The starting price: £90,000.
Lithium-ion batteries have become the technology of choice for EVs, and falling costs and rising energy levels could keep them on top for nearly two decades.
Making improvements to existing engines, as well as working toward something entirely different.
A young(ish) guy that I’ve known for a number of years, a man who spent the better part of his career writing for auto buff books and who is a car racer on the side, mentioned to me that his wife has a used Lexus ES Hybrid.
