The revised Jeep Renegade has been spied undergoing testing in the extreme cold of northern Sweden.

Unlike the recently-revealed Cherokee facelift, the Renegade's mid-life update doesn't seem to be quite as dramatic a makeover.

Up front, the revised Renegade looks as though it will keep the round headlight design seen on today's model. The slats in the updated grille look to be wider, and the indicators have been moved towards the outer edge of the car, while the fog lamps have marched in the opposite direction.

A large amount of camouflage has been used on the rear of the vehicle. Although we can't discern any changes at the moment, we expect the updated model to feature detail changes to the tail-lights and rear bumper.

Infotainment technology has moved on since the car's introduction in 2014, so it's likely the revised Renegade will be available with updated media systems, possibly incorporating larger touchscreens with smartphone mirroring tech like Apple CarPlay and Android Auto. Interior trim fiddles are almost a certainty.

It's not entirely clear when the revised Renegade will arrive down under, but given the brand's current woes in Australia, it can't come soon enough.

In 2017, Jeep Australia recorded sales that were down 34.5 per cent compared to 2016. The Renegade was the second least popular vehicle in the range, if you exclude the the solitary Patriot sold in Australia last year.

With 704 sales (down 33 per cent), the Renegade was behind the Grand Cherokee (5356, down 16 per cent), Cherokee (1069, down 48.6 per cent) and Wrangler (997, down 22.3 per cent), but ahead of the Compass (143, down 87 per cent due to the model switchover) and Patriot (1).
