Tweaked styling hides a thoroughly-overhauled interior for smallest Porsche SUV. As for power? They're not telling us...

Porsche has officially unveiled the 2019 Macan at an event in Shanghai, bringing it up to date with a tweaked look and more technology.

Changes to the car's exterior really are subtle up front, headlined by tweaked headlights and revised air intakes. There's also a range of new colours: Miami Blue, Crayon and Dolomite Silver Metallic adding more choice to the palette for buyers keen to stand out.

Down back, the slim tail-lights of the outgoing car have been replaced by larger units, linked by a Panamera/Cayenne-style light bar in the middle. Porsche is writ large across the rear, in script similar to that used on the 718 Cayman and Boxster. The family resemblance is strong with this one, folks.

Bigger shifts have occurred behind the wheel, where the centre console has been thoroughly overhauled to match the larger Cayenne's design.

The air vents have been shifted to below the touchscreen, replacing vertical units integrated into the dash, while the 8.0-inch touchscreen has been subbed for an 11.0-inch unit running the latest Porsche Communication Management infotainment system. A GT sports steering wheel is optional, complete with an integrated drive mode switch.

The addition of a Connect Plus module to the entire range means the entire range is 'networked', which opens the door for real-time traffic updates and smarter voice control as standard. Off-road driving experiences can also be logged through the 'Offroad Precision App', if you ever feel the need to take your Macan off the beaten track.

Although it says the new Macan has an 'optimised' chassis, and claims the Macan will 'consolidate its exceptional status as a sports car in the compact SUV segment', Porsche hasn't revealed exactly what has changed under the skin.

We know staggered tyre sizes will be standard, and we know a range of new 20- and 21-inch alloy wheels will be offered. Traffic jam pilot, which operates between 0 and 60km/h, has been added to the options list, and will help with low-speed steering – but that's a tech tweak, not a real chassis change.

It also hasn't confirmed what will power the new model, leaving us to speculate over whether the existing 3.0-litre and 3.6-litre twin-turbo V6 engines will remain in the Macan S and Turbo respectively, or whether the 2.9-litre V6 from the Panamera will replace them. Place your bets.

The new Macan will touch down in Australia during the first half of 2019. Stay tuned for more on pricing and powertrains closer to launch.
