So one-minded is any Caterham Seven that each individual model in the assortment feels like a would-be racer lacking only an opportunity.
But Caterham does offer you committed racing Sevens, with none a lot more focused than the cage-bedecked, slick-shod, windscreen-considerably less Championship British isles Racecar. Ignore the unromantic identify: we have driven a single and adored it for its amazing capability to be pleasurable and forgiving when sensation grittily raw and millimetre-exact.
Alas, it’s exclusively for the monitor, which is wherever the new 420 Cup arrives in. Caterham needs you to imagine of this car as the ultimate road-legal trackday 7, impressed by the single-seat Championship racer but with stable concessions to ease and comfort and flexibility.
Inside you will duly find Alcantara trim on the transmission-tunnel, and even the optional composite Tillett seats are heated. The roll-cage (of which there are three varities – Keep track of Day, Activity and Race) is also only an decide-in element, even though a person you could want. This automobile has the Race cage, which as properly as stiffening the overall body, arrives the racer’s metal boot address, and also functions as plinth for wing mirrors that give the Cup the competition-completely ready look. Brain you, it also regulations out getting a windscreen, which the lesser cages don’t. As conventional the 420 Cup comes with a trackday roll-bar, which is effectively a cross of metallic at the rear of the cockpit.
Other racing nods increase to the Schroth harnesses, central petrol-filler and a vented nose-cone noticed only on the madcap 620R and the wonderful 420R Donington Edition of 2017. Nonetheless, wherever only 10 of the Doningtons have been at any time made, the 420 Cup will be series creation. Observe, although, that even with Caterham’s Gatwick showroom a short while ago getting converted to a 2nd creation facility, the lead time for automobiles is approaching a 12 months and earliest 420 Cup deliveries will be in 2023.
That is the window-dressing. The correct temptation of the 420 Cup is the driveline and suspension. As with the racer, the 620R and the Donington, the Cup comes with Sadev’s punchy (savage?) six-speed sequential ’box, which feeds an LSD in the De Dion rear axle.
Energy is from the very same by natural means aspirated, dry-sumped 2.-litre Duratec engine located in the racer, only with additional oomph: 210bhp plays 175bhp. Peaking at 7600rpm, this is the same tune you will obtain in the normal Seven 420, and offers the 560kg Cup absolutely 375bhp per tonne.
The suspension is then managed with anything new for any highway-legal Caterham Seven: manually adjustable Bilstein dampers that sit inside Eibach springs. These are pretty uncomplicated 10-way units with an integrated adjustment for both equally bump and rebound but they imbue this 7 with good adaptability.
For instance, though semi-slick Avon ZZR Severe tyres are an possibility, for trackdays you could conveniently go a single phase even more and slip on some complete slicks. Dial the dampers to their firmest location and hey-presto you’re in touching length of the Championship racecar experience. Similarly, if it is really a moist underwheel, for road-driving you may well enjoy it risk-free with the normal Avon ZZRs and set the dampers to reassuring suppleness.
