You probably don’t know what this thing is, but that’s OK – neither did we. Well, it’s the ‘Low Sodium Roadster’, originally built by Vintage Hammer Garage and having raced over dry terrain every year since 2005, recording a top speed of 274 mph (397 km/h).

It’s currently being auctioned off on Bring a Trailer, although its engine and transmission aren’t currently fitted. The drivertrain is mid-mounted beneath a modded 1927 Ford steel roadster body, comprised mostly of hand-formed aluminum panels.

According to the ad, an MSD 6AL ignition is included in the sale, as is an electric water pump, electric fuel pump, 31-spline rear axles, a 2.75:1 rear diff, lead ballast, roll-over switch, 15-inch racing wheels, four spares and dual 12V batteries.

Inside, the land speed racer obviously boasts a very utilitarian dashboard, containing cylinder head temp gauges, an AFR gauge, tachometer and a boost pressure gauge, plus the essential dual fire suppression systems and parachute.

Back in 2012, the car joined the Bonneville 200 mph Club after posting a two-way average speed of 245.505 mph (395.101 km/h). Between 2005 and 2017, the Low Sodium Roadster set over 20 land speed records at Bonneville, as well as the El Mirage Dry Lake, with six of those records still standing today.

Whoever ends up with the winning bid, we reckon they’ll either race it or simply put it on display. Either way, they will get a very interesting, and rather unusual, piece of kit.
