Mercedes-Benz AMG GT vs Porsche 718

What's the difference?

Once upon a time, people would dream about owning a Mercedes-Benz 450SLC – the C107 sports/luxury coupe flagship of the 1970s.

Sexy, stylish, secure and incredibly solid, it embodied the brand’s ‘Engineered Like No Other Car' mantra of the era.

Today’s all-new, second-generation, C192 AMG GT Coupe is something of an indirect descendant of this sort of thinking, changing tack from its supercar-esque 2014 C190 predecessor, with more space, more seats, more sensibility and, conversely, even more steak and sizzle from its glorious V8.

A modern-day SLC? The Porsche 911, Aston Martin DB12, Maserati GranTurismo and Bentley Continental GT’s worst nightmare? Or something else entirely?

These questions and more are answered below.

“If this is to be our end, then I would have them make such an end as to be worthy of remembrance.”

King Theoden may have been talking about the men and women of Rohan in The Lord of the Rings, but he could have just as easily been talking about the team behind the Porsche 718 Boxster.

It’s been nearly 30 years (yes, that long) since the Boxster joined the Porsche line-up as the more affordable sports car alternative to the 911, but now it’s facing a dramatic change that will make it a very different beast.

Porsche has committed to an electric future for the 718 but before it does so, there was one more petrol-powered version to create, this one, the 718 Spyder RS. It stands to be the final 718 to have an internal combustion engine, but could also be the best.

The 718 Spyder RS is the Boxster version of the previously released Cayman-based GT4 RS. So it takes every element of the sports car and turns it up to 11. This is faster, more powerful, lighter and more dynamic than the Boxster has ever been.
