The McLaren is powered by a 4.0-liter twin-turbo V8 that produces 765 horsepower. The Lamborghini, on the other hand, uses a naturally aspirated 6.5-liter V12 engine paired with three electric motors to deliver a total of 1,015 horsepower to all four wheels. So, the Roelto is a much more powerful car, which, combined with the all-wheel drive system, gives it an edge over the rear-wheel drive 765LT. Of course, the McLaren is much lighter than its two-ton Italian rival at 1,465 kilograms, which makes up for its lack of power. Which one do you prefer?
