Less than two years after the official debut of the Senna, McLaren has announced the next entry in its Ultimate Series of hypercars, the Elva. Joining the F1, P1, and Senna, the McLaren claims the Elva to be the lightest road car it has ever made, with a wild windshield-less roadster body style and an 804 horsepower version of the 4.0-liter twin-turbo V8 found in the P1 and Senna. The design and Elva name come from the open-cockpit customer race cars built in the '60s by McLaren and British race car maker Elva, with a limited production run of 399 units. The open driver compartment features a system of vents and active aero vanes that create a low-pressure zone for the driver and passenger, meaning a helmet isn't necessary — although a windshield will be available as an option. McLaren claims the Elva will be even faster than the Senna, with customer deliveries starting in late 2020.
