BMW X3 £40,880
The XDrive 35d version of BMW’s award winning X3 SUV is a good alternative to the SQ5. Though this is the quickest diesel X3 currently on sale, its acceleration time is still a little slower than the Audi. This X3 takes 5.8 seconds to complete the 0-62mph sprint which means it doesn’t quite have the same supercar pace as the Audi. Powered by a 313bhp 3.0-litre V6 diesel, it has a very similar engine to the SQ5 though it’s cleaner and more economical, returning 46.3mpg and emitting 162g of CO2, but it’s less refined. It is less expensive too.

Porsche Cayenne S Diesel £59,053
Porsche’s Cayenne S Diesel is significantly larger than the SQ5 and feels it. But like the SQ5 it offers an attractive mix of performance, practicality and economy in a premium package. It has a 382bhp 4.0-litre V8 diesel engine up front which can power it from zero to 62mph in 5.7 seconds. Though this is slower than the SQ5 it certainly feels fast to drive and it can return 34mpg (though I achieved 30mpg in real-world use). If you can wait for it, a smaller SQ5-sized compact SUV Porsche model, called the Macan, will go on sale early next year.

Range Rover Evoque from £32,705
If it’s a stylish diesel SUV you’re after then you can’t get better than the Range Rover Evoque SD4. The problem is, in this company at least, it isn’t particularly fast, though unlike its competitors there’s a three-door coupe version if that’s your thing. The 190bhp diesel-powered SD4 can travel from 0-62mph in 8.5 seconds, though that looks fairly pedestrian here. The cabin has set a new standard for premium compact 4x4 cars. If only Range Rover made a seriously fast diesel Evoque – a genuine rival to the SQ5 – it would be easily the most desirable car here.
