THINK high-performance Euro sedans and you end up mulling over acronyms and letters - AMG, M and RS – the three specialist performance offerings from Mercedes-Benz, BMW and Audi. There are, of course others, but for grown up professionals with children these cars help maintain the rage. They’ll happily doddle around town for every day chores but unleash them on the open road and you’re in for a furious, fun time. Mercedes-Benz’s latest AMG63, based on the revised E-class lineup, makes family motoring that much more exciting, and the latest revisions to steering and suspension only serve to sharpen up its act.
