These things don’t often end well.
Two years ago, we pitched a new 266bhp Peugeot RCZ R against a used 503bhp Jaguar XKR – both worth about £30,000 at the time – and the Peugeot came away with a very bloody nose. It was a good car, but simply not good enough against Jaguar's bristling super-coupé. Goliath flattened David and his little sling.
This time, our plucky underdog is the Subaru BRZ – the modestly powered but endlessly exploitable compact coupé, newly refreshed for 2017. Its opponent streaks in from left field in a cloud of combustive noise: it’s one of Peter-Wheeler-era TVR’s finest, the Tamora-derived T350t (the wee ‘t’ denoting a targa-style top, as opposed to the T350c coupé). Fewer than 500 T350s were built, but there are a few in the classifieds, mostly priced at around the same £26,495 being asked for a new BRZ.
The privately owned T350 we’ve generously been lent is worth a little more – about £32,500 – because it carries both Red Rose and Lightweight specification. Red Rose means its six hot Lancashire pots have been stroked, raising engine capacity from 3.6 to 4.0 litres and power from 350bhp to 380bhp, plus heftier brakes, a big-bore exhaust and a viscous limited-slip rear differential. The Lightweight spec means vinylester bodywork rather than the standard GRP, saving about 30kg. That leaves the 197bhp, 1242kg Subaru 142kg heavier yet half as powerful. In starker terms, it’s 159bhp per tonne versus 345bhp per tonne.
