How the Dodge Charger SRT Hellcat compares to the world's other fast sedans

American sports sedans have long suffered from comparison with the European competition. On the autobahns, Mercedes-Benz, Porsche and BMW regularly battle for supremacy in a virtuous evolution of the species; on American interstates, you might as well be comfortable cruising at 70 mph.

But just as American muscle cars demonstrated decades ago that high performance didn't require high European prices, the Dodge Charger Hellcat and its 707-hp engine would appear, on paper at least, to make high-speed hash of some sports sedans that cost more than $150,000.
