McLaren W1 completes over 3,000 miles of hot weather testing in Arizona

The McLaren W1 was subjected to intense hot weather testing in Arizona. A team of engineers drove the hypercar for more than 3100 miles (5000+ km) in temperatures exceeding 104°F (40°C).

According to McLaren, the tests focused on validating critical systems, including cooling, engine load management, and cabin climate control. It is one of the crucial phases in the development of the W1, before customer deliveries can commence.

Earlier, the W1 underwent cold-weather testing deep inside the Arctic Circle in Sweden. The W1’s chassis and systems were optimized during the tests. Its engine, gearbox, battery and electric motor were stress-tested in the sub-zero conditions.

The McLaren W1 uses an all-new 4.0-liter V8 hybrid powertrain that produces 1258 hp and 988 lb-ft of torque, with a redline at 9200 rpm. This makes it McLaren’s most powerful and highest-revving road car powertrain ever and is paired with an 8-speed automatic transmission. The W1 weighs just 1399 kg, resulting in a power-to-weight ratio of 911 PS per tonne. The result is 0-124 mph in just 5.8 seconds.
