Subaru’s formerly all-conquering Forester has come off the boil, with the Mazda CX-5 doubling its sales. So a limited-edition tS flagship is coming, with an STi-tuned performance chassis.

WHAT IS IT? The Forester tS is basically the top-line XT turbo with an STi-tuned chassis and several other mods to improve handling and body control. It is thus a unique proposition in the medium SUV segment, or will be when sales start in May.

WHY WE’RE TESTING IT The Forester has long been regarded as a great all-rounder, avoiding many of the pitfalls of its top-heavy rivals thanks to the low centre of gravity afforded by its boxer drivetrain. But outputs from the big turbo units in Forester XTs (and their GT predecessors) have never quite gelled with the SUV chassis. Can the STi crew help?

THE WHEELS VERDICT Will we finally see an affordable SUV that truly drives like a hot hatch? The upcoming Forester tS is certainly shaping up to be that car, and the differences between it and the mechanically similar Japan Domestic Market-spec Forester XT were pronounced around a tight bitumen track designed for racing bicycles. We had way less body roll and a whole lot more control than usual. How any of that translates on Australian roads from next May is uncertain, but the basic ingredients suggest a performance crossover worthy of the WRX – if not STi – badge.

PLUS: Less cumbersome than XT, Q-car performance, value for money MINUS: Awkward styling, unappealing interior plastics, predicted hard ride and road noise

Whether Fuji Heavy Industries intended on demonstrating this with a Japan domestic -spec Forester XT, pitching it (literally) against the STi-tuned tS around the 5km long, 2020 Tokyo Olympics bicycle training track, is not known. However, the former felt like a loose handful against the latter’s controlled confidence, suggesting that SUV buyers seeking proper dynamics don’t have to fork out $100K on an Audi SQ5 or Porsche Macan.

Unsurprisingly, this STi parts-bin raid results in a more hunkered down Forester that’s hungrier for corners, far flatter when driven fast through them, and a whole lot surer in its reactions and responses. Over exactly the same snaking route, the XT seemed floatier.

Questions do remain about how such a well-tied SUV will ride on our rubbish roads, however. At least extra soundproofing helps hush the thing. FHI says the aim is to promote “on-road tough, speed, and class, so drivers at every skill level can enjoy”.

Speaking of which, while the tS may not arrive with more power than an XT, improvements to handling, roadholding and refinement point to Australia’s first properly WRX-esque medium SUV.
