It should be the automotive equivalent of a swear jar: tip a dollar every time someone remarks the Toyota 86 desperately needs turbocharging. The tin would be flush with enough cash for a Lexus RC200t.

Both are Japanese two-door four-seat rear-drive coupes. Both score 2.0-litre four-cylinder engines, but the posh Toyota adds that all-important hairdryer to its own in-line (rather than horizontally opposed) unit.

A healthy 180kW and 350Nm allows Lexus late entry into the premium-manufacturer downsized-plus-turbo party, without looking as though it has brought a Kylie CD to a hipsters’ record convention. Torque lathered on strong from 1650rpm to 4400rpm? Yep, come in, RC200t.

It is deathly quiet inside, its front seats are excellent and the cabin is loaded. The adaptive suspension strikes an excellent balance between luxury and sports – particularly on 35-aspect 19-inch tyres– in Comfort, Sport or Sport+ modes.

Those bank-vault suspension components may help explain the RC’s terrible weight problem though, because somehow this compact coupe with non-existent rear legroom weighs 1675kg.

Lexus RC200t engine

Lexus claims a 7.5-second 0-100km/h, only a tenth quicker than (gasp!) an 86. A 1470kg BMW 428i coupe with identical outputs is 1.7 seconds faster, while an RC350 shades the 200t by 1.4 seconds. The 350’s 3.5-litre V6 also revs beyond the turbo’s soft 6200rpm redline, and is sweeter and likely to be no thirstier (the turbo four recorded 13.6L/100km on test).An RC350 F-Sport also gets four-wheel steering and a variable-ratio rack that helps it feel nimble and pointy, but it hasn’t been engineered for the $3K-cheaper RC200t F-Sport, which is grippy yet blunt as a result. The Torsen LSD now standard on both sports grades is also pointless when the stability control scuppers even subtle throttle moves.
