Budding tarmac and gravel racers listen up: Subaru Australia has released first details and images of its latest WRX STI-based race car, which was first announced in July and is now open for expressions of interest.
Priced from just $38,000 including GST but excluding delivery – making it more than $11,000 cheaper than the WRX STI on which it’s based – the motorsport-only sedan is available in three performance tiers.
All cars are prepared by Subaru Australia’s long-term motorsport partner, Possum Bourne Motorsport (PBMS), offering more power, less weight and a host of race-ready extras over the standard STI.
The entry-level 2015 WRX STI NR4 (pictured), the first of which was prepared for Subaru Australia and will soon be displayed at Subaru Interactive @ Docklands, weighs just 1480kg and is powered by an exclusive 2.0-litre turbo boxer engine producing 227kW at 6400rpm and 422Nm at 4400rpm — up from the 221kW/407Nm of the local 2.5-litre STI.
Similar to the road-going STI, the racer sports helical front and DCCD-equipped centre differentials, with a 41/59 front/rear nominal torque split that can be biased via a three-mode SI Drive system.
The non-road-registerable NR4’s standard 3.9:1 final drive ratio remains and massive 17-inch Brembo brake discs are fitted all-round, sitting behind 18-inch alloys shod with 245/40/R18 tyres.
Aimed at club-level racers, the Tier 1 NR4 also features OMP winged seats, OMP six-point harnesses, OMP steering wheel, PBMS seat runners, gunmetal grey interior paint, PBMS fibreglass centre console panel for window switch, PBMS fibreglass door panel set, PBMS fibreglass radio panel, PBMS fibreglass rear parcel tray and PBMS fibreglass driver’s foot tray, while the interior sound deadening and airbags are removed and window switched relocated.
Two exterior paint colours – white and WR Blue – are available and customers will need to fit an FIA-approved roll cage, which can be ordered at the time of purchase for fitting pre-delivery.
The WRX STI NR4 cars are FIA-homologated and eligible for FIA WRC2 (one rung below the elite World Rally Championship level), ERC2 regional and progressive national championships, as they meet the FIA’s new NR4 regulations, which replace the previous N4 and R4 classes.
In addition, there are six option packs, covering engine, brakes, driveline and suspension, plus specialised gravel and tarmac packs.
“The attention to detail on this car is just amazing and it’s a compliment to PBMS that they have only honed their skills further since they partnered us in producing 10 consecutive years of Australia Rally Championships.,” said Subaru Australia managing director Nick Senior.
Expressions of interest should be directed to email@example.com quickly, because only a limited number of base cars will be imported and already eight have been sold.
