Hi-po SUV will set you back $149,900 before on-road costs when it arrives in January.

The wider Alfa Romeo Stelvio range has been on sale in Australia since the middle of 2018, but we've been eagerly awaiting the arrival of the range-topping Quadrifoglio performance hero.

Well, it'll be here in January, and it'll cost $149,900 before on-road costs, a $6k premium over the related Giulia Quadrifoglio sedan.

Power comes from a Ferrari-derived twin-turbo 2.9-litre V6 making 375kW and 600Nm, out to all four wheels through Alfa Romeo's Q4 all-wheel drive system. That means it'll hit 100km/h in just 3.8 seconds, on the way to a top speed of 283km/h.

The car sends power to the rear wheels in normal conditions, but can shoot 50 per cent of the engine's drive to the front axle when slip is detected. By way of comparison, the Giulia QV sedan is rear-drive all the time.

On the active safety front, the hottest Stelvio gets forward-collision warning, autonomous-emergency braking, adaptive cruise control, lane-departure warning, blind-spot monitoring, a rear-view camera, and parking sensors all around.

Both driver and passenger sit in eight-way power-adjustable front seats trimmed in Alcantara and leather, while the dashboard and door panels are wrapped in leather to match. There's a heated sports steering wheel, carbon-fibre trim, aluminium pedals, unique scuff plates, and four-leaf clover floor mats.

The car rides on 20-inch forged alloy wheels as standard, behind which hide red brake calipers. You can pay $700 to have them painted black or yellow, while carbon-ceramic stoppers are a $12,000 option.

While we're talking options, a dual-pane sunroof is $2400, carbon-backed front seats are $5000, and a slicker (leather, Alcantara, carbon) steering wheel will set you back $500.

Metallic paint is an extra $1300, while flagship tri-coat colours are a $3500 option.
