How to defeat the powerful and dominant McLaren 720S in a rolling drag race? Use a car that has more power and intensity than it, that’s the only answer.
But if you ask Hennessey Performance this question, they may give you a more specific answer: just use the Corvette ZR1 HPE1200 and you will win for sure. Yes, why not? The American tuner makes some of the quickest cars on earth, so they know it very well that the modified ‘Vette is strong enough to put an end to the 720S’s domination.
Recently, we’ve seen how well the Corvette ZR1 performs on the dyno. Its supercharged 6.2-liter V8 managed to put out as much as 1139 hp and 994 lb-ft of torque to the rear wheels. It’s a far superiority if you compare it to what the 720S has at its disposal: 710 HP and 568 lb-ft at the crank. While real testing has repeatedly proven that the British supercar is more potent than that, it still doesn’t have what it takes to threaten the ZR1.
Hence, it’s almost unsurprising that the ZR1 could easily take the triump. Nonetheless, we have to admit that the 720S has put forth commendable effort to close the gap, since the supercar wasn’t all that much slower than the wildly-tuned ZR1 despite their vast difference in power figures. Besides, the outcome of this battle might be different if both of them were put on the circuit – a place where more than power is needed to go fast and the 720S might very well have been able to keep up.
An even fairer fight can be imagined if what the ZR1 opposed wasn’t a stock 720S, but the one equipped with Hennessey’s HPE1000, which is the company’s best package the supercar can get. As the name suggests, the kit bumps power to 1000 hp after it’s installed. That much of output would give the McLaren the ability to deal with the ‘Vette properly.
