Everything You Need to Know About the McLaren W1’s Powertrain

Team TopGear India got on a call with the research and development team of the McLaren W1 team. We learnt a lot of things about the W1, and boy-oh-boy, this is a rocket ship! Here is everything you need to know about the McLaren W1.

McLaren W1 Engineered to break records and dominate the track, the McLaren W1 is a hybrid hypercar designed to deliver an adrenaline rush the moment you press the accelerator. McLaren’s goal with the W1 is to make every journey as thrilling as the destination. Built on McLaren’s core supercar principles—Performance Everywhere, Epic Power Delivery, Pure Driver Connection, and Authentic Theater—the W1 is an exclusive masterpiece, limited to just 399 units, all of which have already been sold.

Performance & Driver Engagement

Development of the W1’s MHP-8 engine began in late 2020, with the first prototype ready by late 2022. Over the past 3.5 years, the engine has undergone intense physical testing.

One look at the W1 makes it clear: this car is built to conquer any racetrack. McLaren has leveraged its expertise from Formula 1, Formula E, and IndyCar to craft this engineering marvel.

Key Performance Specs:

  • Engine: 4.0L Twin-Turbocharged V8 Hybrid

  • Transmission: 8-speed Dual-Clutch

  • Power Output: 1,258 bhp

  • Torque: 1,340 Nm

  • 0-100 kmph: 2.7 seconds

  • 0-200 kmph: 5.8 seconds

  • Top Speed: 350 kmph

McLaren’s goal wasn’t just raw power—it was engagement. The W1’s engine is designed to make every drive exhilarating, with a meticulously tuned sound profile that builds to a crescendo at the rev limit. Engineers focused on eliminating unwanted mechanical noise while enhancing the powertrain's most thrilling sounds.

Driving Modes

Despite its staggering performance, the W1 remains a road-legal car, so it comes equipped with distinct driving modes to ensure versatility across various driving conditions.

  • E-Mode (Electric Mode) is perfect for stealthy driving. It allows you to leave home silently at night before switching to internal combustion power.

  • Comfort Mode The default startup mode is optimised for relaxed city driving, with the electric module used only for smooth torque delivery.

  • Sport Mode Fully deploys the E-module for maximum hybrid power, featuring ignition-cut gear shifts and a more responsive throttle.

  • Race Mode Delivers the highest combined power output from both the combustion engine and E-module.

  • Grand Prix Mode Optimized for track sessions, balancing E-module deployment and energy harvesting for consistent performance over extended runs.

Conclusion

The McLaren W1 is an engineering marvel. We have just scratched the tip of the iceberg here. If we were to explore its technology more deeply, this article would become a full-fledged technical manual. For those who missed out on owning one of the 399 units, don’t worry; we will be getting more hypercars with the same engine from McLaren.
