2019 Alfa Romeo 4C Summary

Nothing could’ve better prepared me for my drive in the 2019 Alfa Romeo 4C than a trip to Sydney’s Luna Park.

There’s a rollercoaster there called Wild Mouse - an old-school, single carriage coaster with no loop-the-loops, no high-tech trickery, and with each ride limited to just with two seats apiece.

The Wild Mouse throws you around with very little regard for your comfort, gently impinging your fear factor by making you consider the physics of what is happening underneath your backside.

It’s an unbridled adrenaline rush, and genuinely scary at times. You get off the ride thinking to yourself, “how the hell did I survive that?”.

The same can be said with this Italian sports car. It’s blisteringly quick, it’s superbly agile, it handles like it has rails attached to its underbody, and it could potentially do brown things to your underpants.

Verdict

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).

Verdict

People might wonder if there’s a reason to buy an Alfa Romeo 4C. It has some great dollar-for-dollar competitors - the Alpine A110 does most of the things the Alfa does, but in a more polished way. And then there’s the Porsche 718 Cayman, which is a considerably more, well, considered option.

But there is no doubt the 4C stands alone, a sort-of cut-price alternative to a Maserati or Ferrari, and nearly as rare to spot on the road as those cars, too. And just like the rollercoaster at Luna Park, it’s the sort of car that’ll leave you wanting another go.
