The often more familiar comparison here is between a Ferrari and a Lamborghini. Since the Lamborghini Huracan is still only available as a coupe, the Ferrari 458 Spider didn't really have serious competition. That is until McLaren launched the 650S Spider at Geneva earlier this year. A significant improvement over its 12C predecessor, the 650S Spider is still powered by a twin-turbocharged 3.8-liter V8, but output was been increased to 641 horsepower.

The 458 Spider packs 562 hp thanks to its naturally aspirated 4.5-liter V8. Obviously the McLaren is a slightly more modern machine, but Ferrari will soon strike back with the rumored (and highly probably) 458 Speciale Spider. In the meantime, those in the market for a European supercar featuring a lightweight retractable hardtop have two solid choices. Let us know your preferred choice in the comments and poll ahead.
