The 765LT is powered by a twin-turbocharged 4.0-liter flat-plane-crankshaft V8 engine that is mounted right behind the seats. Spin it up and you'll get 755 horsepower and 590 lb-ft of torque, which is 45 hp and 22 lb-ft more than the 720S.
McLaren's reps claim a 0-60 mph time of only 2.7 seconds and we're inclined to believe them. Mashing the accelerator from a stop results in a brief pause as the seven-speed dual-clutch automatic transmission begins to slip the clutch, followed immediately by a considerable burst of power as you're pinned to the seat.
That alone is satisfyingly excessive, but it's just the prelude. A blink of an eye later, as the revs push past 5,500 rpm, the turbochargers kick in with the kind of aggression we'd expect from an F-15's afterburners. The world outside blurs from the speed and vibrations from the vehicle while the 765LT launches with laser-straight precision.
The LT sheds speed with similar expertise. Jump on the brakes as hard as you can and the nose twitches ever so slightly but continues on its intended path. The big rear wing flips to the vertical position, acting as an air brake. This position also adds considerable aerodynamic downforce to increase rear tire grip. You feel the soft tissue in your body try to escape out the front as you brace against the dead pedal and steering wheel, yet the nose of the car keeps from diving toward the pavement.
As capable as these brakes may be at full potential, they also allow for nuanced modulation. Feathering the brakes as you nudge the vehicle toward an apex is easy, and there's no noticeable transition to the throttle if executed gracefully. The transfer of weight between the front and rear is well managed, and the overall balance is as perfect as you'll find for high-speed cornering.
And corner it does.
The 765LT has an abundance of grip. The kind that you get from a legitimate race car wearing track-only slick tires. A lot of that can be attributed to the wide 305-series Pirelli P Zero Trofeo R tires at the rear, but the active suspension and aforementioned downforce also contribute mightily. On public roads, you'll feel every imperfection in the road surface. But the suspension absorbs most big jolts, keeping all four wheels firmly planted. On smooth surfaces, the 765LT really begins to prove itself with otherworldly handling limits. The ultra-precise steering with substantial feedback serves to further add to driver confidence and enjoyment.
Whether you're a white-knuckle death-grip type of pilot or a racing sophisticate with a featherlight touch, the McLaren 765LT will engage you and reward you with each passing kink in the road. It goes blisteringly fast and corners with cartoon-like ease, just as intended. It thrills as it challenges the driver to give it more, but it's also relatively easy and approachable for a supercar. It's not overly twitchy or terrifying, just impeccably balanced.
If you're seeking a race car for the road (and you've been in an actual race car before), this is it. If you're looking for anything different, such as comfort or refinement, you'd probably be better served by almost any other supercar. Don't take that as a knock against the McLaren, though. Rather, consider it affirmation of its hardcore nature. Yes, we love it.
