Aston Martin Valiant is an ultra-rare, front-engine V12 halo car built on the Valour platform that Fernando Alonso helped shape.

It uses a twin-turbo 5.2-liter V12 making 735 hp and 555 lb-ft, sent to the rear via a six-speed manual.

Fully allocated to a handful of clients, the track-focused Valiant contrasts with mid-engined hybrids like the Valhalla.

Fernando Alonso rolled past the Casino de Monte-Carlo this week in a car most people will never see in person: a black Aston Martin Valiant with round LED daytime running lights and a rear spoiler that looks borrowed from a race car. It is not his only exotic in town.

The two-time Formula 1 champion was also spotted driving his Aston Martin Valkyrie around Monaco in recent days, but the Valiant is the rarer sighting by far. The latest clip comes via an Instagram video highlighted by TheSupercarBlog, which shows the car easing away from the casino at night.
