Say Hello to McLaren’s New Halo Hypercar

Say Hello to McLaren’s New Halo Hypercar

On the 50th anniversary of McLaren winning its first Formula 1 World Championship, it is officially debuting its newest hypercar, the McLaren W1. To say the W1 has been highly anticipated would be an understatement. The new hypercar can draw its lineage straight back to the legendary McLaren F1 of the early ’90s, and it is the direct successor to the McLaren P1. Those are big wheels to fill, to say the least. Let’s dive into McLaren’s newest halo car.

McLaren’s Most Powerful Engine

Just behind the driver’s seat in the W1 is the most powerful engine McLaren has ever produced. Though, to be fair, we would expect nothing else from a car that’s meant to take over as the top dog. Like the P1 before it, the McLaren W1 has a hybrid powertrain blending a 4.0-liter 90-degree V-8 and an “E-Module” that has a radial flux electric motor. If the term “radial flux” sounds familiar, that’s because it’s the same technology Koenigsegg uses in the “Dark Matter” electric motor in the Gemera.

The flat-plane-crank V-8 engine, which McLaren calls the MHP-8, makes 916 horsepower and 664 lb-ft of torque. The electric motor adds another 342 hp and 324 lb-ft, bringing the grand total to 1,258 hp and 988 lb-ft of torque. The McLaren W1 sends every hoof of that horsepower to the rear wheels via an eight-speed dual-clutch automatic transmission and electronic locking differential.

For those who don’t feel like doing the math, the W1 has a 354-hp and 324-lb-ft advantage over its predecessor, the P1. The W1’s V-8 alone makes as much torque as the entire P1’s hybrid powertrain.

Electrify All the Things

The McLaren W1’s E-Module is fed by a dielectric immersion-cooled 1.384-kWh battery with “motorsport-derived” cells, according to McLaren. The W1 keeps the battery at a minimum level of charge so that it can crank the motor, and—get this—reverse the car. That’s right, the McLaren W1 has an electric reverse gear called “E-reverse.” This sounds wild, but most Toyota hybrids have been operating this way for years—using one of their electric motors spun the other way to move backward.

The entire E-Module (the radial flux electric motor and integrated motor control unit) weighs just 44 pounds and mounts to the side of the transmission.

The McLaren W1 can be driven in electric-only mode, but as you may have guessed by the size of the battery, it can’t go very far. All-electric range is just 1.6 miles, which will get you far enough from the neighbors so that they don’t complain when the V-8 kicks in.

Wait, who are we kidding? Anyone who can afford this car either has enough private land that their nearest neighbor couldn’t hear them, or their neighbors also have hypercars that are just as loud.

All About Airflow

Considering what McLaren does on the weekends, it’s no surprise that it put a massive effort into the W1’s aerodynamic design. McLaren says the W1’s aerodynamic platform is the most advanced its ever created for a road car. The final design comes after over 350 hours of wind tunnel sessions and 5,000 metrics tested.

Everything hangs on what McLaren calls the Aerocell monocoque, the shape of which is meant to facilitate the W1’s ground effects. As you might be able to see in the interior images, the seats are integrated into the monocoque in a similar way to a Formula 1 car. McLaren says integrating the seats in that way saved it 2.8 inches in wheelbase requirement. Like the F1 and P1 before, the W1’s driving position is changed by moving the pedal box in the raised footwell.
