The McLaren W1 (codenamed P18) is a sports car from the British automobile manufacturer McLaren Automotive, set to be produced from 2025. It is the heir to the McLaren F1 and McLaren P1.

The McLaren W1 was presented on October 6, 2024.^[2][3]

The W1 is based on the McLaren Carbon Lightweight Architecture (MCLA) carbon fiber architecture.

Weighing 1,399 kg (dry) and with a maximum power of 1,275PS, the McLaren W1 has a power-to-weight ratio of 911 PS/tonne.

Mclaren said that it is the fastest accelerating road-legal McLaren ever, reaching 100 km/h (62 mph) in 2.7 seconds and 200 km/h (120 mph) from standstill in 5.8 seconds. The declared top speed is electronically limited to 350 km/h (220 mph).

Costing US$2.1 million, only 399 W1s will be built.^[4]

The W1 is powered by a hybrid powertrain that incorporates a 4.0-litre twin-turbo flat-plane crank V8 engine, designated MHP-8, and an E-module that comprises a radial flux E-motor and MCU (Motor Control Unit) to enhance throttle response and performance: with combined outputs of 1,275 PS^[5] and 1,340 Nm,^[6] the powertrain delivers the highest power and torque figures ever from a Mclaren Automotive powertrain.

The V8 engine is the most powerful combustion engine from McLaren Automotive, producing 928 PS and peak torque of **900 Nm**. The E-modules develops up to 347 PS and 440 Nm.

This enables performance of:

• 0–200 kilometres per hour (0–124 mph) in 5.8 seconds
• 0–300 kilometres per hour (0–186 mph) in under 12.7 seconds

The vehicle is also capable of zero tailpipe emissions driving on electric power alone.

The W1 features a cooling system designed to maintain optimal performance under track conditions. It incorporates:

• Three separate water glycol circuits operating at different temperatures.
• A high-temperature circuit with four radiators for engine cooling.
• A low-temperature circuit for charge cooling.
• A dedicated hybrid cooling circuit for the E-module, battery, charger, and DC/DC converter.
• A total of 10 heat exchangers to manage various cooling needs, including HVAC and oil cooling.

Powertrain Modes

The W1 offers multiple driving modes to optimize performance across different environments:

• Electric Mode: Near-silent EV operation.
• Comfort Mode: Default mode for relaxed driving.
• Sport Mode: Full hybrid power with engaging throttle response.
• Race Mode: Maximum power for short sprints.
• Grand Prix Mode: Consistent performance throughout a track session.

The W1 features an all-new eight-speed dual-clutch transmission (DCT) designed to handle high torque levels. An advanced hydraulic E-differential directs power to the rear wheels, enhancing driver engagement and performance.

The W1 is designed with a focus on ground-effect aerodynamics, featuring:

• An underbody designed to maximize airflow and downforce, stemming from McLaren’s Formula 1 Team
• Active aerodynamic elements, including a front splitter and rear wing, which adjust to enhance performance.
• Total downforce limited to 1,000 kg, achieved through extensive wind tunnel testing (over 350 hours and 3,000 CFD simulation runs).

The W1 features an electric module and battery,

The W1's E-module, derived from motorsport technology, contributes up to 347 PS and is mounted beside the transmission. It features:

• A 1.384 kWh battery designed for rapid power delivery.
• Active Aero stemming from multiple downforce controls using the spoiler and front bumper.
• Second-generation dielectric immersion cooling for effective thermal management.
• Onboard charging capability, allowing the battery to be replenished to 80% in just **22 minutes**.

The McLaren W1 is rear-wheel drive, reflecting the brand's racing heritage and engineering expertise. The vehicle emphasizes lightweight construction, optimal weight distribution, and finely tuned dimensions, which enhance performance and driving dynamics.

The McLaren W1 has been praised for its performance, innovative technology, and striking design. As a limited-edition model, it represents the pinnacle of McLaren's engineering achievements and is highly sought after by collectors and automotive enthusiasts. Only 399 are announced to be made, and the manufacturer is said to have sold out on launch.
