Caterham has introduced a new, enhanced version of its Superlight R300 race car, offering greater performance with reduced running costs.
Already established as the top of the Seven racing ladder, the 2-litre, 175bhp machines will now be equipped with a Sadev six-speed sequential gearbox, replacing the existing manual unit. The new gearbox utilises flat-shifting electronics, allowing clutchless up-shifts, resulting in faster, more precise gear changes and even closer racing.
The new version of the R300 has also switched from the Avon CR500 to the Avon ZZR, a longer-lasting tyre which offers higher performance through improved grip levels. Tyre use throughout the season remains limited to just five sets for the season, which, along with the newer, more robust transmission, keeps running costs low. The all-new Avon ZZS tyre will be used in wet conditions.
“The Sadev gearbox, which is used in the 310bhp 620R road car, is a cutting-edge piece of engineering and it suits the R300 perfectly,” explained Chief Motorsport and Technical Officer of Caterham Cars, Simon Lambert. “It’s extremely robust and gives the series a new dimension. We are looking forward to bringing back sequential gearboxes to Caterham racing – the feedback we have received from the drivers has led us to develop the new Superlight R300 race cars. It’s a win-win scenario because not only will lap times be faster, but it should prove to be extremely robust, too, meaning that along with the durable ZZR tyre, entrants can expect improved reliability and reduced costs.”
Priced at £32,495, the R300 is available to order now, with the 2014 season kicking off on April 19 at Snetterton before going on to visit Donington Park, Belgian circuit Zolder, Brands Hatch, Rockingham, Croft and Silverstone.
The new, improved R300 will be on display at this weekend’s Autosport International show at Birmingham’s NEC.
