Dodge Challenger
The third element of the famous American triumvirate, the SRT8, is anything but discreet, though more docile versions are available. Base models use the well mannered V6 with a five-speed automatic. Tame V8 versions come with a 5.7L engine, while the wild SRT8 has the 410-hp 6.4L. All V8 versions come with either a five-speed automatic or six-speed manual gearbox.
