Caterham R300 Superlight unveiled

By Ben Pulman First Official Pictures 28 October 2008 10:30 Caterham has released its latest Superlight Seven model, the R300. Powered by a 2.0-litre Ford Duratec engine, tweaked by Caterham Powertrain to produce 175bhp, the new R300 will sprint to 60mph in 4.5 seconds.  The new R300 weighs a mere 515kg, just 15kg more than CAR’s long-term 1.6-litre Superlight. Combined with the new 175bhp engine, the R300 has a power-to-weight ratio of 339bhp-per-tonne – a Porsche 911 Carrera S has a mere 270 by comparison.
