Gen 4 Subaru WRX arrives in Australia

As a flagship for Subaru, the WRX always comes with high expectations. In this instance, a much more aggressive appearance and more ferocious performance was expected. While some may argue that the latest WRX failed to deliver on both fronts, the performance and driving dynamics of this latest version have led some to label this version as the best 'Rex' ever.

Two basic versions are offered: the WRX sedan and WRX Premium sedan. Unlike previous generations, the WRX will only be available as a sedan, with no hatchback version offered.

As the name suggests, the WRX Premium offers a higher level of specification, with features over the standard WRX, including leather seats (with 8-way power operation for driver's seat), in-dash satnav, Harman-Kardon audio system, push-button starting, an electric sunroof, dusk-sensing headlights and rain-sensing wipers.

Mechanically, the two versions are identical, with a 2.0-litre turbocharged boxer four-cylinder powering both. Despite being smaller than the 2.5-litre engine it replaces, the new 2.0-litre produces more power: 197kW @ 5600rpm, with an impressive torque figure of 350Nm @ 2400-5200rpm. It's more fuel efficient, too, with Subaru claiming 11.5-percent better economy than the incumbent.

The main new feature of note with the Gen IV WRX is the addition of a CVT transmission option, the first time an Impreza/WRX has been offered with a self-shifter for ten years.

The Sport Lineartronic Continuously Variable Transmission features paddle-shift operation for the 6 standard ratios, but select the 'Sport#' mode, and eight ratios are on offer. With this 'manual' mode option, this latest CVT is claimed to offer the latest in Subaru transmission technology. The standard transmission is a 6-speed manual, one more cog than the manual tranny on the outgoing model.

Somewhat surprisingly, the CVT delivers greater top speed than the manual (240kph vs 215kph), but the 0-100kph sprint is a fraction slower, at 6.3 seconds, versus 6.0 seconds flat for the manual.

Handling, based on impressions from the launch drive tests in Tasmania, is sublime, and went a long way to this WRX receiving the "best ever" tag. The chassis has been stiffened up, with stronger cross members, and overall rigidity improved by a claimed 40 percent. Combined with the WRX's signature AWD, this means a very high level of roadholding and ultra-flat cornering. Despite this stiffness, the ride isn't as bone-jarring as you may expect. Sure it's firm, but it's far easier to live with as a regular driver than its performance credentials may suggest.

The cabin has been treated to some improvements inside, too, with a more modern, more premium feel to the plastics, seats and dash and console trim, even on the base model. Importantly, the sports seats offer good support, while the steering wheel is reach and rake adjustable.

While the WRX Premium features the aforementioned satnav and Harman kardon audio, the standard WRX unit features a single CD with MP3/USB/AUX connectivity and six speakers. Intelligent Tune technology, with voice image control, virtual bass and sound restore moves vocals directly in front of occupants, without disrupting stereo balance.

A shallower windscreen rake equals better front three-quarter vision, as the A-pillars are further forward, with small quarter windows added. While the basis is definitely towards front seat passengers, there's still respectable room in the rear seats, along with a more than respectable boot capacity of 460 litres.

Exterior styling is certainly more aggressive at the front, but quite subdued at the rear. To some minds, the front and rear treatments don't really match up, but that probably comes from enthusiasts being used to the chunky diffusers and bold rear spoilers of previous generation WRXes. Ten-spoke 17-inch alloys are the standard fitment, with a finer 15-spoke design available as an option. Seven exterior colours are available.

Now available in Subaru dealerships Australia-wide, pricing for the new WRX starts at $38,990 for the standard manual. The CVT adds $2,000 for $40,990. The manual trans WRX Premium carries a $43,990 pricetag, while the CVT WRX Premium tops the range at $45,990*.
