These are the latest spy images of the Porsche Macan, spotted hot weather testing.

Two test cars were spotted in this latest set of photos, with the standard car testing alongside the Macan Turbo. The Turbo version has subtle styling changes from the standard Macan, including larger front air intakes and two lines of daytime running lights. Although both cars have been pictured with minimal camouflage, parts of both the front and rear light clusters are still disguised.

The car has previously been spotted testing in the Arctic Circle and at the Nürburgring. A production version is expected to be launched in October. The styling influences of the larger Cayenne are clear in the five-door Macan, the car effectively looking like a shrunken version of its bigger brother.

The Macan has a low, wide, stance and is sleek in profile, traits helped by its sharply raked windscreen and sloping roofline. The Macan is likely to measure around 4600mm long, 1890mm wide and 1650mm high, making it 210mm shorter, 50mm narrower and 40mm lower than the larger Cayenne.

Underpinning the Macan is Volkswagen Group’s next-generation MLB platform for large front- and four-wheel-drive SUVs. Audi has been heavily involved in the platform’s development, and it will also be used to underpin the next-generation Q5.

The engine range will be crowned by a new twin-turbocharged V6 with around 370bhp and 400lb ft of torque. This new engine will power the Macan Turbo, which aims to carve out a niche as a faster, more dynamic alternative to the BMW X3 and Range Rover Evoque.

At the bottom of the engine range will be two four-cylinder engines – the first time four-cylinder powerplants would have appeared in a Porsche since the 968 in 1995.

On the petrol side, there will be a 220bhp 2.0-litre unit that should still be good for 0-62mph performance of 7.5sec and a 143mph top speed. The base diesel will be a 190bhp 2.0-litre turbo unit.

Other engines in the Macan’s range are set to include a 295bhp 3.6-litre V6 in the S, and a 250bhp 3.0-litre V6 in the Diesel S. A Macan Hybrid is also planned, and Porsche is also keen to use Audi’s potent new 309bhp twin-turbocharged 3.0-litre V6 in a Diesel Turbo model.
