The data has dropped on Benz's new AMG GT coupe, and from spec sheet to marketing spin, it's clear the GT has that other German sportscar, the Porsche 911, in its three-pointed gunsight.

With a projected local launch of June 2015 we're still some time away from official prices and equipment levels, but with a projected starting price of $250,000, that puts up against the $245,700 911 Carrera S.

How do they compare?

We're speculating on price, but judging by the brand cred, performance and luxury on offer, it wouldn't be unreasonable for Mercedes-Benz Australia to ask a quarter-million for the entry Mercedes-AMG GT.

 

AMG GT vs 911 Carrera S

The 911 Carrera S is slightly cheaper ("slightly" being a relative term, given the six-figure pricetag), but the GT trumps it in almost every metric.

Power? The GT's twin-turbo 4.0 litre V8 makes 340kW against the Carrera S' 294kW atmo flat-six.

Torque? Again, the Mercedes monsters the Porsche with 600Nm - 160Nm more than the 911.

What about speed? Well, the Mercedes-AMG GT runs from zero to 100km/h in 4.0 seconds, while the 911 Carrera S does it in 4.3 seconds.

That's despite the Porsche having a weight advantage of 105kg.

Top speed for the GT is a heady 304km/h, slightly ahead of the Carrera S' 297km/h V-max.

 

AMG GT S vs 911 GT3

With the more performance-focused GT S, we can only assume its rival will be the $293,600 911 GT3.

Even against Porsche's legendary motorsports-honed GT3, the AMG GT S compares favourably.

The GT S pumps out 375kW and 650Nm while the GT3 produces 350kW and 440Nm.

The AMG claims a 0-100km/h sprint time of 3.8 seconds, with a top speed of 310km/h - 5km/h less than the GT3.

And, despite its lower outputs, the GT3's lower kerb weight (1430kg for the Porsche, 1570kg for the AMG) sees it hit 100km/h in just 3.5 seconds.

As handling goes, the AMG GT has the right stuff for a sports car. With its engine positioned well behind the front wheels and its rear-mounted gearbox providing a 47:53 front-to-rear weight distribution, the GT is no lead-tipped arrow.

In the GT S, handling is also enhanced by a torque-vectoring active limited slip differential and huge 390mm brakes.

There are other tech tricks too, like adjustable dampers for the GT S, optional carbon-ceramic brakes and active engine mounts - all of which are available on the GT3 too, though the Porsche also adds rear-wheel steering.

But what about things like steering feel, ride comfort and lap times? Those are much harder to compare, and are things that can't be done by staring at a set of spec tables.

We'll have to wait until next year to put the new Mercedes-AMG GT to the test, and though the stats look promising it remains to be seen just how well it will fare against one of the most legendary sports cars of all time.
