Aston Martin takes the Valour to the extreme with more aero, more power, and less weight.

Aston Martin has unleashed a new road-legal track car upon the world. Meet the Valiant, an aero-heavy supercar based on the company's already magnificent Valour coupe. Staying true to Aston's edict that big engines are what people want, it uses a twin-turbo V-12 making over 730 horsepower. And it's paired to a six-speed manual transmission.

Think of the Valiant as Aston Martin's version of the Porsche 911 GT3 RS. It's a hotted-up, sportier variant of the Valour designed for performance over comfort. According to the company, the idea came from none other than Aston Formula 1 driver Fernando Alonso, who asked for a vehicle like this as a personal commission.

As such, the Valiant has been equipped with a boatload of aerodynamic add-ons, including a reworked front end with a big splitter, a fixed wing out back, and a seriously large diffuser. The bodywork, reshaped to improve airflow, is made entirely of carbon fiber. The 21-inch magnesium wheels are covered in a set of aero discs to improve aerodynamics around the car, inspired by Aston's RHAM/1 that raced at Le Mans in the late 1970s. They shroud a set of carbon-ceramic brakes measuring 16.1 inches in diameter up front and 14.1 inches in the rear.

There are even more changes under the skin. The Valiant uses a 3D-printed rear subframe, a titanium torque tube, and a lightweight lithium-ion battery, together cutting 51 pounds. The Valour's suspension has been thrown out in favor of a set of Multimatic Adaptive Spool Valve (ASV) dampers, super-fancy equipment that Aston says is "capable of simultaneously adjusting each damper to one of thirty-two discreet damper curves in less than six milliseconds." It's the type of super-fancy stuff you'll find on the Ford Mustang GTD, the Ferrari Purosangue, and modern IndyCars.

The 5.2-liter twin-turbo V-12 inside the Valiant makes 735 horsepower, 30 more horses than the Valour. Torque is unchanged at 555 pound-feet, a result of torque limits for the gearbox, according to an Aston spokesperson. The six-speed is a transaxle mounted out back for better weight distribution. Like in the Valour, the limited-slip differential is a purely mechanical unit.
