The XR-3 Hybrid is a super-fuel-efficient two-passenger plug-in hybrid that achieves 125 mpg on diesel power alone, 225 mpg on combined diesel and electric power, and performance like a conventional automobile. The design of the XR-3 Hybrid focuses on existing technologies and a vehicle “personality” that makes conserving energy a fun driving experience. It showcases the design ideas explored in Robert Q. Riley’s book, Alternative Cars in the 21st Century.
At just 1300 pounds, this high-performance design combines lightening-fast acceleration, a maximum speed of 85 mph, and fuel economy of 125- to over 200-mpg.
Its clam-shell canopy and three-wheel platform boldly differentiates the XR-3 from conventional passenger cars. The vehicle’s hybrid power system, diesel engine, and low curb weight are the main ingredients of its super-high fuel economy and excellent performance. Acceleration equal to that of a conventional car and a maximum speed of 85 mph make the XR-3 Hybrid equally at home on freeways and surface streets.
We had no reason to offer any further proof that Japan is the unquestionable winner when it comes to wacky inventions, but the Melody Road convinces us our judgment is completely accurate. The Melody Road will allow a car passing above it to play a simple tune, which is made audible by ridges on the road's surface. The pitch of the note created is increased by increasing the frequency of the ridges, and the opposite is also true. Jump for more details, and a completely baffling video.
The Typ-1e and the Typ-1h
Underneath the sweeping lines of the aerodynamic shell, the Typ-1 hides some very well thought-out technology to make the driving experience comfortable and safe as well as being incredibly fuel efficient.
The all-electric model has a range of 120 miles with a regenerative braking system operational through the rear wheel in addition to full dual system hydraulic brakes front and rear. Despite the prevailing attitudes towards the performance of electric vehicles the Typ-1e is by no means sluggish – it achieves a top speed of 90mph and accelerates from 0-60 in around 10 seconds. The Typ-1h hybrid version significantly steps up the range covering more than 600 miles with fuel economy at a staggering 300 miles per gallon.
