The UK’s Autocar reports the Seven line-up will be simplified with a numerical naming system, based on a model’s power-to-weight ratio.
This formula has already been adopted with the Seven 160 and Seven 620, which will continue to serve as entry-level and range-topping models respectively.
Current models names - the Supersport, Roadsport and Superlight - will reportedly be scrapped in favour of the new system.
Caterham is said to be appealing to more customers with its new system, by providing an easy performance differential based simply on the model’s numerical name.
But the British carmaker isn’t simply ‘badge engineering’ with its new system, with the trio of new models reportedly receiving performance upgrades and revised styling over the models they replace.
To further enhance its range, Caterham will then offer both ‘S’ and ‘R’ option packs on all five of its 2015 Seven models, with the ‘S’ pack offering the most performance.
Previously, the Seven 620 R was the most ‘extreme’ model the carmaker had ever offered, so it remains to be seen how the new 620 S will better the R’s already-impressive 2.8 second 0-100km/h time.
Caterham reportedly plans to launch the first of its new Seven models in the UK market around Q2 of next year, while the CSR will continue to be sold as a ‘stand-alone’ variant.
In Australia, Caterham currently offers the Seven, Roadsport and CSR models.
