It is something of a left-field choice for towing duties, but the Infiniti FX does a good job of pulling a caravan.

For one thing, there’s no shortage of poke. The 3.0-litre diesel engine has 405lb ft of torque, enough to pull a heavily laden twin-axle tourer from 30-60mph in just 11.7 seconds.

The Infiniti is also stable at speed, with little movement at 60mph or beyond, even with a stiff wind blowing from the side.

Strong brakes add to the Infiniti’s towing credentials, stopping car and caravan in just 10.7m and with little drama.

However, the FX was found out in the lane-change test, with the caravan tugging hard at the back of the car on high-speed runs.

As a solo drive, the FX gets a mixed scorecard. It’s certainly quick, but the ride is bone-jarring and there’s too much road noise for a luxury SUV with a £50k price tag.

For such a huge car, there is little space for rear-seat passengers or for gear. Our practicality judges couldn’t find space for a typical load of holiday luggage. What’s more, we found the towing electrics awkward to reach.

Poor economy and disappointing resale values make the FX hard to recommend, despite its striking looks and powerful engine.
