Porsche Cayman vs Alfa Romeo 4C

5 Feb, 2014 12:13pm

After years in the wilderness, Alfa Romeo has a thoroughbred mid-engined sports car again. Can it beat the Porsche Cayman?

Alfa Romeo is an enigma. Famed for making some of the world’s most beautiful cars, this company has a sporting heritage that stretches back nearly a century.

Alfa Romeo 4C review

Porsche Cayman review

Yet with the exception of the limited-edition 8C supercar, it’s been decades since the evocative brand has made a sports car that truly lives up to its illustrious past. The new 4C changes that. Its specification is pure supercar – carbon-fibre chassis, dual-clutch gearbox, mid-engine layout – but it costs less than £50,000. And with a 237bhp, 1.7-litre turbocharged four-cylinder engine matched to a featherlight kerbweight, unassisted steering and rear-wheel drive, it promises to be scintillating to drive.

Yet for a similar amount of cash, you could get your hands on one of the best sports cars on the planet: the Porsche Cayman. In fact, the 271bhp 2.7-litre entry-level Cayman is cheaper and more powerful than the Alfa, so you’ll be able to dip into Porsche’s long options list with the money you save.

The Cayman also promises to be a lot more practical, refined and comfortable than the 4C. However, will this focus on everyday usability blunt the Porsche’s appeal when compared to the razor-sharp Alfa? We pitch the pair head-to-head on road and track to deliver the definitive verdict on one of the most eagerly awaited performance car bouts of the year.


On track With its hard set-up, the Alfa is more at home on a track than the road. You quickly discover strong lateral body control and lots of grip, and can enjoy high-speed changes of direction. Yet in medium-speed corners, the stiff front end understeers too much, and the transition to oversteer is snappy. There’s lots of stopping power, but the brakes lack feel. The Cayman is more adjustable and agile. Which was quicker around Lincolnshire’s Blyton race track? Our video at www.autoexpress.co.uk reveals all.


The Alfa is only offered with a dual-clutch box, while Porsche sells its similar PDK set-up as a £1,922 option. That still makes the Cayman cheaper to buy than the 4C – although the standard manual box has a great shift action.


Few brands can rival Porsche and Alfa Romeo for sports car kudos and motorsport heritage. Alfa has lost its magic in recent times, but in the thirties, fifties, sixties and seventies, its sports cars were lusted after the world over. Racing Alfas were originally famed for their part in classic road races like the Targa Florio and Mille Miglia, and they battled Porsches for class and overall wins in world championship sportscar racing right up to the mid-seventies.

Worth considering

Lotus Exige S The Exige S is closer in character to the 4C than the 4C is to the Cayman. The Lotus delivers more power from its V6 engine, although it’s much more expensive, with a price tag of £52,900.

1st place - Porsche

The Cayman is a fantastic all-rounder. It’s incredibly composed on the limit, and equally engaging and sharp at low speeds. It’s also more comfortable and refined than the Alfa, as well as cheaper to buy. And while it’s a bit slower than the 4C, cabin quality is superb and its everyday versatility is unrivalled. 

2nd place - Alfa Romeo

The 4C is a stunningly attractive sports car and a welcome addition to struggling Alfa’s line-up. But thanks to its unflinching focus on lightness and performance, it’s so raw you’ll need to be a purist to put up with the lack of refinement – and it still can’t match the sweet handling of the Porsche Cayman.

POS both! Give me a 2 ton JAAAAAAAAG FAT-Type for just £70k!

F-Type Coupe for me, more powerful, better looking and not much more expensive.

What a load of rubbish this test is. The Alfa and Porsche are made to attract different customers.

No mention of the fact that on the track Alfa 4C is faster than the more expensive Porsche Cayman S, and much faster than a normal Porsche Cayman at the same price!?

[edit] faster in independent tests, also officially faster around the Nüerburgring.

Wrong again.
You are not very good at this are you?

Yes, all correct and it's also better suited to normal road use which is what most of us do most of the time.

Can you please provide a link to these 'independent' tests which prove the 4C is officially faster round the Nüerburgring? Ta.

Having seen the Alfa 4C at the Top Gear hanger on Wednesday, I can say it looks absolutely stunning and that's about it, it's very minimalist, the seats are quite nice, but that seems to be all there is going for it.

As for the £40k price tag, I thought they were having a laugh.

Well, there´s as always lot of journalist blah blah blah about which car ist more "refine" and about "responsive" or "unresponsive" steering, their feelings of how it drives and, and, and.
What´s interesting here for me is, how does the 4C really perform on track (since to judge it by its daily driving capabilities is ridiculous for me, it can obviousle only be considered as the 2nd or 3rd car) - just hard facts, no blah blah blah

And from this perspective the Alfa is a SERIOUSLY FAST CAR. The best comparison offers the german "Sportauto"-Magazine, since the Nurburgring-times have all been recorded by Horst von Saurma = same driver - different cars, making the laptimes somehow comparable. And here they are:
Boxster S (2009) – 8:18
Boxster S (2012) – 8:04
Cayman R (2011) – 8:10
Cayman S (2006) – 8:25
Cayman S (2009) – 8:17
Cayman S (2013) – 8:05
Jaguar XKR-S (2013) – 8:03 (550 HP !)

Saurma has achieved a 8:04 time with the 4C last year.

Other times are also quite impressive.
Vairano (quattroruote - there´s a video on their page): Alfa Romeo 4C: 1:18.84

Balocco (another italian car magazine): Alfa Romeo 4C 2:54.43

So for me, objectively, the 4C is a serious car for me, not to mention the fact, that despite its not having a V6 enginge (which would be nice, I admit) and the 1.8 TBI not being a real cracker, it can be easily (and inexpensively) tuned up to about 280 BHP...well...still having to pull only about 1.000 kgs of mass.

I´m really seriously considering buying one, I like it.


The 4C holds the Nurburgring record for cars under 250PS, and posted the same time as the Cayman S (8:04).
You can read about it on this website.

Not much more? Think again.
