Bollinger Motors unveils electric sport truck chassis for on and off-road performance
11 April 2017 - Autoblog
Electric truck startup Bollinger Motors is working on its first vehicle, and plans to unveil it this summer.
There hasn't yet been that much information available about the company's prototype truck, other than teaser images, but the ground-up design is slowly being revealed. Now, the all-aluminum chassis has been unveiled, and it's said to weigh only 295 pounds, while reportedly remaining structurally and torsionally rigid.
Instead of reworking an existing design to suit their needs, the engineers at Bollinger say they have sketched the chassis and the vehicle to be a credible electric sport truck from the beginning. As it needs to act as a showcase for their electric all-wheel-drive system, Bollinger says it should be capable both on and off road, rattling off measurements believed to be optimal for off-roading. The truck will have a wheelbase of 105 inches, a 68-inch track, an approach angle of 56 degrees, departure angle of 53 degrees, and break-over angle of 33 degrees.
It offers 15.5 inches of ground clearance, but that is adjustable with a self-leveling independent hydropneumatic suspension, which sounds interestingly Citroën-like, but used in a truck application. There is 10 inches of wheel travel available, and disconnectable anti-roll bars allow full suspension articulation when off-roading. The truck's hydraulic steering rack is an in-house design, so that Bollinger could get it fine-tuned the way they wanted it.
The chief engineer at Bollinger, Karl Hacken, says the chassis enables the battery storage system to be mounted as low as possible, with a low center of gravity in mind. Since the truck appears to be an engineer's dream first, it will be interesting to see what kind of body Bollinger has decided to craft for it. Their no-nonsense approach and the accompanying image of a cardboard model suggests a Defender-like, butch and blocky appearance.
