At first glance the SR3 SL still looks like a pitlane refugee, but closer inspection reveals there are areas where it departs from the Radical norm. The existing SR3 is Radical’s most popular car – more than 600 have been sold – and while they can be made road legal, many are not and that is not their ethos.
The SR3 SL, though, is different. The ‘SL’ in the name stands for Street Legal; instead of the IVA single-vehicle type approval process that has previously been applied to the SR3 (limiting the number of cars that can be road registered to 300), the SL has been through the European type approval process.
This allows Radical to make up to 2000 cars and sell them throughout the EU – and mainland Europe is where much of the demand has come from. It’s not a simple process, and it isn’t cheap (Radical has invested in the region of £750,000 doing it).
Visually, there are some obvious changes, such as broader radii around the front splitter and the cockpit edge. The rear wing is narrower so that it doesn’t reach the body’s edges, and the wheels sit further inboard than usual. They all lend the SL a slightly odd look that’s less pure than other Radicals. It looks less fast.
