LAMBORGHINI AVENTADOR LP750-4 SUPERVELOCE
362kW/tonne. With 552kW from its 6.5-litre V12 the LP 750-4 earns its place at the top with muscle, upping the ante from 515kW in the regular (and heavier) Aventador.
McLAREN 650S COUPE
359kW/tonne. It’s about lack of weight rather than outright power with the 650S. At just 1330kg, the twin-turbo 3.8-litre V8 (the only turbo in this list) can hit hard. Racier 675LT version raises the bar.
FERRARI 458 SPECIALE
331kW/tonne. Last of the atmo Ferrari V8s still delivers thanks to 441 purebred kilowatts, especially mated to the stripped-out Speciale body. Coming 488 ups the ratio to 341kW/tonne.
327kW/tonne. Ferrari’s most powerful model musters 541kW from its screaming 6.3-litre V12. Now, where’s that autobahn…
305kW/tonne. What it lacks in punch (okay, we’re being cruel, because there’s still 449kW to play with) the 5.2-litre V10 makes up for with its 1474kg kerb weight.
