Hennessey-Tuned McLaren 600LT Has Bugatti Veyron Level Of Power

Feb 7, 2019

There are three levels of upgrades, and the top one boasts 1,001 horsepower.

The McLaren 600LT's production only lasts 12 months, but Hennessey now offers power upgrades for the limited-run, hardcore model for any owners who want to give their rare machine a big increase in output. In the top HPE1000 trim, the 3.8-liter twin-turbo V8 makes 1,001 horsepower (746 kilowatts) and 865 pound-feet (1,173 Newton-meters) of torque, rather than the stock figures of 592 hp (441 kW) and 457 lb-ft (620 Nm).

"I decided to buy my 600LT for the same reason I bought a new Ford GT to give our team a solid benchmark for our Venom F5," company boss John Hennessey told Top Gear. After driving the McLaren, he decided "it was "asking for is more power" and had his team get to work on upgrades. Hennessey thinks the 600LT with the HPE1000 could be a performance threat to the McLaren Speedtail hypercar.


To obtain such a significant power upgrade for the 600LT, Hennessey installs revised turbos, a high-flow wastegate, new exhaust hardware, an upgraded intercooler, high-flow air filters, and Motec engine management. Tweaks to the seven-speed gearbox make sure the transmission is strong enough to handle the extra muscle.

Hennessey claims that a 600LT with the HPE1000 package can reach 60 miles per hour (96 kilometers per hour) in 2.1 seconds and cover the quarter mile in 9.6 seconds. A stock example of the McLaren hits 60 mph in 2.8 seconds.

Hennessey also offers less powerful tunes for the 600LT. The HPE 800 pack bumps the output to 805 hp (600 kW) and 722 lb-ft (979 Nm). The company claims it gets to 60 mph in 2.4 seconds and sprints through the quarter mile in 10.1 seconds.

There's also the HPE 700 version with 708 hp (528 kW) and 635 lb-ft (861 Nm). Reaching 60 mph requires 2.6 seconds, and a run through the quarter mile takes 10.5 seconds.

Hennessey doesn't offer pricing for these packages. However, owners can afford a 600LT's base price of $240,000, then they probably aren't too worried about spending a little more to boost their new car's performance to hypercar levels.
