It’s more stable. Most modern three wheel vehicle designs have recognized the advantages and adopted this approach.
Why front wheel drive ?
Two driven front wheels provide double the traction of a single rear wheel. It’s safer and allows much higher performance vehicles. Attempting to driving full power through a single rear wheel cannot provide adequate traction. Imagine accelerating on an on-ramp, losing rear tire traction, and spinning into the guardrail or traffic (yikes!).
Why do others have rear wheel drive ?
Unfortunately, a single drive wheel requires the least engineering and is cheap to produce. But the stability issues give three wheelers a bad reputation.
Why have the engine in the rear ?
More optimum weight distribution, which is key for three wheelers. The most weight is located at the widest part and most stable part of the car. A side benefit is that it allows for better looking vehicles.
What's does the "100% fun" mean ?
The forward seating provides an entirely new level of excitement. The connection with the road is akin to driving a motorcycle. Some people have said it’s like flying. Others have said it’s the best thing since a rollercoaster. One thing for sure… it’s entirely unique and 100% fun!
