Overview: With its stubby styling and revolutionary carbon-fiber/aluminum structure, the i3 takes BMW’s driving principles to a new realm. For example: In our testing, it went from zero to 60 mph in 6.5 seconds. Driving dynamics are on hand, too, thanks to the car’s low center of gravity. The EPA estimates the range at 81 miles per charge; it can charge in three hours from a 220-volt outlet. An optional range-extending gas engine provides a total range of 150 miles and helps quell dead-battery anxiety.
The extensive use of bare carbon fibre has kept the weight to a minimum The KTM X-Bow Superlight is one of the variants of the KTM X-Bow model range. As the name suggests the Superlight is the lightest model in the range - but not by much, the base model KTM X-Bow is just 5 kg (11 lbs) heavier. Although the Superlight is a full 40 kg (88 lbs) lighter than the GT4 version. The weight reductions to the KTM X-Bow Superlight have been made possible through the extensive use of carbon fibre. The monocoque structure with integrated crash protection is composed entirely of carbon fibre and left unpainted to show of the carbon fibre weave. The few body panels which are fitted to the X-Bow Superlight are also formed from carbon fibre. Additional weight savings were also achieved through the use of unique light-alloy wheels finished in a dark lacquer. Powering the KTM X-Bow Superlight is the same Audi-sourced 2.0 litre turbocharged engine found in all the X-Bow models. This engine puts out 24...
