In part, interior quality deserves praise, too. The upper sections of the dash, the door cards and the dash and door trim inlays are soft to the touch and the metallic bits are suitably stout. However, the plastics further down the dash and centre console are less convincing, and being forced to embrace a lot of Mercedes' electronics and switchgear isn't good for perceived quality.
Inifiniti's own infotainment system is hard to get excited about, too. The standard 7.0in colour touchscreen can also be controlled using a rotary dial and shortcut buttons between the front seats, and DAB radio, Bluetooth and voice control feature on every model. Screen graphics are sharp, but the system lacks the responsiveness or latest connectivity apps of its best rivals, while the clunky sat-nav is a £1400 option even on our mid-range Premium Tech car.
Still, Premium Tech trim does include features such as leather seats, climate control, keyless entry, a rear-view camera, two USB ports and, like all Q30s in the range, city braking technology as standard.
Should I buy one?
There's far more reason to consider a Q30 over its competition that any other Infiniti to date. Subject to confirmation in the UK, the Q30 has a reasonably comfortable ride, while its cabin feels largely high in quality and there's a good level of equipment on Premium Tech trim, apart from absence of standard sat-nav.
Infiniti buyers are often investigating something with distinct style outside the staple German brands, and compared directly with Mercedes' A220d AMG Line 4Matic DCT, there are genuine reasons why you might throw your hard-earned at the Q30 instead.
Even so, it's hard to ignore the fact that an equivalent Audi A3 Sportback 2.0 TDI is around £2500 cheaper to buy, considerably faster, just as clean and fuel efficient and better equipped while also feeling higher in quality inside and more engaging and refined to drive.
