Small British sports car makers rarely get a chance to shine on the world stage at major international motor shows. But they can really play to their audience at events such as the Autosport International, as Caterham and Radical have shown this morning.

Both have shown significant new offerings – Caterham with its SP/300.R sports prototype and Radical with its SR3 SL road car – and both punctuated their presentations with tales of success that prove the niche British sports car market is very much alive and kicking.

Caterham will announce figures in the next few days that will show 2010 was a record year for it, both in its sales and profits. It’s a similar story at Radical: in 2010 it sold its 1000th car since its launch in 1997 and it shifted around 200 units alone in 2010.

What both new cars highlight is the understanding the two firms have of their customer bases and their willingness to listen – and respond – to what they’re being told, particularly from new customers overseas who want something different from the firms’ traditional offerings.
