7 Sandwich

There's an obvious risk in claiming a link with Formula One when your F1 cars are perennially fighting for the last two spots on the grid but, in the case of Caterham, it's obvious they know how to make one car very, very well,  the 7.
The 7 is the evolution of Colin Chapman's late 1950's design, meaning Caterham scoff at Porsche for changing design too often.

So it should come as no surprise that ,when it came time to release a new "concept" car, the first new design since...1957.  what they ended up doing is taking a Caterham CSR and sandwich it between two slices of bodywork.
