Honda Project 2&4: If you crossed a car and a motorcycle, you might come up with the Honda 2&4. The four-wheel , single-seat vehicle uses a 999-cubic centimeter motorcycle engine with a 14,000 RPM redline to make 212 horsepower and 87 pound-feet of torque.A six-speed dual-clutch automatic transmission gets that power to the ground, which the occupant seats near. Despite its bike-like weight (under 900 pounds), the 2&4 is tuned for use on public roads.It has an open cockpit and floating seat, and it's the result of a competition among Honda designers. Check it out at the Honda display during the 2017 Chicago Auto show.
