Having hopped straight out of the Mustang GT 5.0 V8 and straight in the Ecoboost model, the latter was always going to feel like it was playing second fiddle to an extent. That said, while it may not be able to match the V8’s 4.3sec 0-62mph sprint time, the four-cylinder Mustang still doesn’t feel particularly slow.
That engine now produces less power than it did in the 2015 Mustang. In the older car, it developed 313bhp at 5500rpm, while 319lb ft of torque was available from 2500rpm. Now, it churns out 286bhp at 5400rpm - although torque has been increased to 325lb ft from 3000rpm. When paired with the new 10-speed auto ‘box, this results in a 0-62mph time of 5.5 seconds - an improvement of three-tenths of a second over its predecessor.
Where it quite obviously loses out next to its V8-powered stablemate, though, is in the soundtrack department. That ‘Coyote’ V8 is one of few remaining naturally-aspirated V8s still available, and the breadth of noises it expels from its quad tailpipes is one of the Mustang GT 5.0’s most endearing features. It’s deep, bassy and menacing at low-revs, and approaching volcanic when you really put your foot down and rev it out. The Ecoboost, meanwhile, makes a largely forgettable noise. There’s a noticeable level of synthetic aural trickery being piped into the cabin to help improve things, but this can only ever go so far.
Still, it’s a smooth and responsive unit, and thanks to the presence of the twin-scroll turbocharger its torque is much more accessible than it is in the V8, being available from 3000rpm as opposed to 4600rpm. The new 10-speed ’box works well enough, and will drop down a handful of ratios with little delay when you need it to - making overtaking manoeuvers that much easier. Our only gripe with it, and it is a relatively small one, is that it can be a bit slow to respond when you use the paddles to manually shift up a gear on full throttle.
On the smooth roads of our southern France test route, the Mustang generally rode well. There was a bit of brittleness at lower speeds, but out on the motorway it was pliant and comfortable, with only a small amount of road noise from those 19in alloys penetrating the cabin. It doesn’t handle with quite the same accuracy of, say, a BMW 420i (although the Mustang will leave it for dead in a straight line), but there’s decent weight to the steering, if only little in the way of feel. Despite the Mustang’s relatively large proportions - it’s a shade longer and wider than the BMW - those MagneRide dampers do a decent job of containing lateral roll through bends, too.
The interior isn’t the last word in upmarket appeal, either, thanks to plenty of scratchy black plastics, but it’s by no means offensive. Recaro bucket seats look the part and are both comfortable and supportive; you’ll just need to be prepared to part with £1,700 to get them, and forgo the standard seats’ heating and ventilation functions in the process.
