The Mercedes-AMG GT R was one of the most exciting cars we tested last year, and now it’s even better thanks to its new folding roof. Taking the same 4.0-liter, twin-turbocharged V8, the GT R isn’t as hardcore as its coupe counterpart, but we’re happy to trade of the coupe’s outright performance for more headroom and unfettered access to the V8’s delicious engine note.
