2018 Ford Mustang GT Convertible review

By Chris Thompson, 18 Jul 2018 Reviews

The best way to hear the 5.0’s trick new exhaust

It takes a certain kind of person to buy a convertible. The convertible buyer isn’t necessarily an extrovert, but they certainly don’t mind (and welcome) the right kind of attention.

So it makes sense that one of the most attention-grabbing cars on the road would be available as a convertible. Sales illustrate that it’s not attention-grabbing because it’s unique, but the 2018 GT’s trick exhaust demands full attention from any red-blooded V8 fan’s ears.

MOTOR performance review: 2018 Ford Mustang GT

Without the roof up, the new Mustang is quite a looker, but most who’ve weighed in think the Coupe is still more handsome.

But if the weather’s good, you’ll want the roof down. Something the Coupe doesn’t allow you is the full brunt of the new four-mode exhaust fitted to the Mustang GT.

The pipes are able to be opened up in any driving mode, meaning you can cruise to the hum of the 5.0’s glory at any pace you like.

Unless you drive one back to back with a coupe in the same place, you’ll likely not notice any blaring differences between the driving dynamics, aside from where the Convertible’s extra weight comes into play.

MOTOR review: 2018 Mustang Motorsport Roush RS3 auto

Ford Mustang onroadUnfortunately for us, winter in Victoria isn’t the best time and place to test drive a drop-top. We only get to spend about a week with most cars we review, often not long enough to see a properly sunny day. So I just had to pretend that, when the roof came down, the weather was nice and warm and bright.

Sure, even with the roof up it’s still an aggro American muscle car with a cracking engine and excellent exhaust, but so is the GT Coupe which costs almost $10K less.
