Everything but the engine
While an economical engine is the heart of a fuel-efficient vehicle, all other components contribute as well. From tires to body styles, here is a look at vehicles technologies that save fuel.
Getting personal
Electronics suppliers are developing systems for cars that help automakers adapt more functions to each driver's preferences.
The lithium-ion charge is on
Multiple engineering trade-offs define the capabilities and limitations of the latest lithium-ion batteries for next-generation hybrid, plug-in, and pure-electric vehicles.
Braking forces
Braking distance is one of the least important criteria when comparing braking systems, even for high-performance applications.
