Three fellows, working at the GM design studio in southern California had a plan. Their goal was minimal weight, distributed 50/50 front and rear including driver, compact dimensions and great handling, with aesthetic appeal and overall efficient design. The result is the SUB 3 Wheeler, powered by a Suzuki TL1000R V twin engine situated next to the driver. They wanted a canyon carver not a drag racer and that's what they built.
The SUB has a handbuilt TIG welded frame, a fiberglass body and three wheels with motorcycle tires. Most 3 wheelers these days have some version of car tires, the motorcycle tires gave them the right contact patch area distribution and weight distribution while limiting frontal area. Their choice was a version of Avon's cruiser tires.
They used an array of high tech tools beginning with the computer models, CNC machining to create the reusable molds and even used some rapid prototyping. The SUB weighs 750 pounds and has 120 horsepower which translates into a lot of fun.
They're considering a limited production run of 25 priced at $80,000 with $25,000 down. This may seem a bit steep but everything on this 3 wheeler is custom made, even the wheels and there are custom choppers out there that cost a lot more. Pretty neat.
