Alfa Romeo has a colourful history dotted with truly remarkable motor cars, but the Fiat-owned manufacturer is currently on a drip-feed.

Its mainstream models have failed to create more than a blip in the sales charts and, bar the achingly beautiful but deeply-flawed 8C supercar, there’s been little to stir the hearts of the diehard Alfisti.

Until now, of course. With a carbonfibre tub, mid-mounted turbocharged four-cylinder engine and rear-wheel drive dynamics, the 4C offers a tantalising collection of ingredients, but can it be the brand’s promised comeback car?

Or is this little more than Italy’s answer to the Lotus Elise, a minimalist tool that only excels on the right road at the right time?

Alfa 4C vs Porsche Cayman 1

Its pace may give the 911 Carrera a fright, but the Porsche the 4C really has to overcome is the phenomenally capable Cayman.

On paper, it looks as though the Stuttgart marque may have an uphill battle on its hands: the Cayman trumps the Alfa with 202kW from its 2.7-litre flat-six, but will struggle to see which way the 4C went in a straight line, taking a relatively leisurely 5.7sec to dispatch the 0-100km/h sprint.

We start this test on the Alfa Romeo test track in Balocco – in the Porsche. The super-sweet, super balanced Cayman excels as there are no rough edges, no abrupt transitions and no nasty surprises – you could accept an incoming phone call while sliding through the esses. The steering is smooth and progressive, the light-footed handling easily modulated and the drivetrain performs in a flow.

If that all sounds a bit predictable, teutonic, boring even, then the 4C quickly provides an adrenaline-charged antidote. Driving the 4C on track is likely to involve more sweaty palms, heavy breathing and trembling fingertips than in the Cayman but, equally, the Alfa driver will also have a bigger grin more often.

Even with all the electronic aids deactivated, the 4C remains an interactive tool that never leaves you in any doubt as to what is going to happen next.

The effort required is spot-on most of the time, but at parking speed the wheel threatens to freeze in your arms. And away from the track and out on the open road, tramlining raises its ugly head; it’s best to just leave the occasionally snappy front end alone and let it sort itself out like a vintage 911.

The Alfa R&D team consciously went down the hardcore avenue, but the 4C’s ride and stability suffer as a result next to the rock-solid yet nicely compliant Cayman.

In fact, approach these two from a pragmatic perspective and one car stands head and shoulders above the other.

Head and shoulder room are not an issue, but climbing in and out of the 4C should be practised in private before you embarrass yourself in public.

In contrast, the Cayman is like a fully furnished luxury flat, with electronically adjustable seats, an ear-bleeding stereo and colour multimedia display, but such opulence incurs a hefty penalty at the weighbridge.

Carrying those extra kilos, in addition to lacking a force-fed torque curve, means that around town the Cayman needs to be belted in the hyperactive ‘Sport-plus’ mode simply to keep the red rocket in sight.

What the Alfa’s turbocharged unit does give you, though, is flexibility. With maximum torque of 350Nm available from 2200-4250rpm, changing gear becomes an optional activity, while the Porsche demands that every last rev be used – get caught a gear too high in the Cayman and the 4C’s pretty Ferrari 458-esque rump will simply disappear into the distance.

The turbocharging also imbues that 1.7-litre four-pot with a unique soundtrack: it’s loud, possibly too loud, with the musicality of the base engine note embellished with furious turbocharger whine, wastegate sneezes and vicious cracks from the exhaust on full-throttle upshifts.

The Alfa is exceptionally pretty (bar those awful headlights, which will surely strike fear into arachnaphobes everywhere) with real centrefold appeal. It’s also almost always the faster car from A-to-B and more fun to drive – while your physical stamina lasts. And therein lies the problem.

Enter the Cayman, with chairs designed for humans, not monkeys; with air-con that can do better than freezing the face while frying the toes; with suspension that doesn’t feel like you’re sitting on a skateboard. It’s the better 24/7 choice, a comfortable and convenient sports coupe for grown-ups.

And yet, as soon as parking space and funds permit a second car, the Alfa Romeo should be on every petrolhead’s shopping list.
