The covers came off the BMW 3.0 CSL Hommage concept at the 2015 Concorso d’Elegance Villa d’Este over the weekend, and there’s much more to the lime green two-door than that oversized rear wing. There’s a smaller, roof-mounted spoiler, also lime green. Plus more swoops and curves than we can count. Most of those are lime green as well. Add in a racing-inspired interior that manages to make room for a luxuriant swath of hardwood on the dash and you’ve got a very striking concept fueled by some serious performance heritage.
