The Japanese manufacturer’s cars are efficient and fun to drive mostly thanks to their revolutionary SkyActiv-G engine technology. Mazda isn’t resting on its laurels, though, and is preparing a whole new generation of SkyActiv-X powerplants. These new engines will be able to use extremely lean fuel mixtures like the homogeneous-charge compression-ignition engines.
For a defunct automaker, Plymouth sure has made its way onto our hot cars list a surprising number of times. If the company had been able to keep building interesting cars like those produced during the muscle car era, it wouldn’t be defunct. Of the hot cars built by Plymouth, the best ever has to be the 1970 Plymouth Hemi Barracuda.
In 1967, the Pontiac GTO had a new engine under the hood. The old 389 had been bored out to become a 400. When the new engine was equipped with a Rochester Quadrajet four-barrel carb(in the high output versions only), it was capable of 360 ponies and 438 lb-ft of torque. The 1967 GTO had an upgraded gearbox as well.
The Plymouth Road Runner made no pretense about being a family sedan with an upgrade package. It was built for balls out speed and delivered in spectacular fashion with the 426 Hemi engine installed.
