Alfa Romeo 4C Spider revealed: Geneva Motor Show

The Alfa Romeo 4C Spider (pictured) revealed in Geneva The Alfa Romeo 4C is the epitome of a modern ‘supercar’, with ultra light weight (for a production car) allowing the 4C to produce very good performance from its modest 17500cc engine. So producing an Spider convertible immediately raises the weight issue in a more dramatic way when the car’s abilities are so dependent on it low weight, but it seems the Alfa Romeo 4C Spider – previewed as a production car with a concept at Geneva today – has managed to keep the wight penalties of the convertible 4C down to a minimum. Thanks to a canvas roof and carbon fibre rollover bars, the weight penalty for the Spider is only about 60kg (around a 7 per cent gain) which shouldn’t hurt performance too much.

Ssangyong getting bullish with the Korando SX

The new Ssangyong Korando SX is to feature in a £1 million TV advertising campaign comparing price and spec with its rivals. It’s almost exactly a year since we reported Ssangyong’s return to the UK market with the Ssangyong Korando, a competitive budget compact SUV they hoped would set them on a path to sales success in the UK. Ssangyong ramped up their Korando offering in June by launching the Korando SX 4×4 at a very reasonable £18,795, although you did have to sacrifice kit – and a lump of power – to achieve the new 4×4 entry price.
