Spider Overview:
McLaren 675LT (Spider). With 700 Nm of torque, it offers ample pulling power. With a weight of 1368 kg, it falls in the mid‑range. Rear‑wheel drive offers dynamic handling and sporty feedback.

3.8 V8 (675 Hp) SSG Verdict:
Performance Verdict
The M838T 3.8L twin-turbo V8 delivers ferocious power and torque, propelling the 675LT Spider to supercar-beating acceleration figures. Its responsiveness and high-revving nature are truly exhilarating.
Fuel Economy
Fuel economy of 11.7 l/100 km combined is respectable for a supercar of this caliber, but it's certainly not a priority for owners. Expect higher figures under spirited driving.
