Alfa Romeo Stelvio N-Ring Edition

Now this is a special car indeed: 1 of 108 Produced. The Stelvio N-Ring Edition is a stunning upgrade to your average Stelvio which itself is already a great car. We were given the chance to uncage this beast on our dyno...

A Stage 1 remap takes the Stelvio Quadrifoglio from 510bhp and 600Nm to around 560bhp and 700Nm on our rolling road. The diesels gain proportionally more: the 2.2 JTD at 150, 160, 180 or 190hp all reach around 220hp and 530Nm, because they are the same engine at different factory settings, and the 210hp version goes to about 230hp and 550Nm. The 2.0 petrol at 200hp reaches around 310hp and 460Nm.

The Alfa Romeo Stelvio is both a great looking car, and a great performing one too. It’s 2.9L twin-turbo V6 engine pushes over 500bhp out of the factory with an unimaginable 600Nm torque. This Stelvio N-Ring edition has the same engine, same gearbox, same drivetrain, but the rest of the car does have some upgrades. The exterior is matte Circuito Gray making for a very striking aggressive look. Carbon fibre trim around the front grille and mirrors compliments this, as well as the de-chromed black badges on the rear. There’s more carbon fibre on the sills between the 20inch wheels which contain the crimson red callipers. There’s only 1o8 in the world, only 12 of which are in the UK. We were lucky to have this one on our dyno to make it even faster. Check out Alfa Romeo’s website for more details about this car.

Stelvio N-Ring Stock Figures

As previously mentioned, the car already runs 500 bhp and 600Nm torque which is already very impressive. To prove this, Alfa Romeo used the car to break 3 UK SUV lap records earlier this year; the Indy Circuit at Brands hatch in 55.9 seconds, Donington Park in 1m 21.1 seconds, and Silverstone’s Grand Prix circuit in 2 minutes 31.6 seconds. These records prove how well the Stelvio has been designed as a ‘sporty SUV’, beating out competitors such as the Jaguar F-Pace, Porsche Macan, Audi Q5 and many more.

That being said, why stop there? We knew that the engine inside this monstrous car is more than capable of coughing up more horsepower and plenty more torque.

Tuned Figures

So after a couple of hours of vigorous tweaking to write the very best map, we run the Stelvio N-Ring one final time. As expected, the car is now producing 560BHP and 700Nm Torque! That’s a very respectable +60BHP and +100Nm Torque, making the record breaking car capable of upsetting even more cars both around the track and in a straight line. We found that this car delivered the power better after out stage 1 tune, making for a less choppy ride, even when driving around town.

If you have a Stelvio that you feel needs that extra punch of power when you need it most, call us now to find out what we can do for you!

Questions we get asked

How much power does a Stelvio gain?

The Quadrifoglio goes from 510 to around 560bhp and 700Nm. The 2.2 diesels at 150 to 190hp all reach around 220hp and 530Nm. The 2.0 petrol goes from 200 to around 310hp and 460Nm, which is the biggest percentage gain in the range.

Why do the 150 and 190hp diesels end up at the same figure?

Because they are the same engine. Alfa sets them at different outputs in software for pricing and insurance, not with different hardware. Once the restriction comes off they both arrive at the same place, which is why the lower-powered car is the better buy if you are going to tune it.

Is the Stelvio Quadrifoglio the same as the Giulia?

Same 2.9 twin-turbo V6 and the same state of tune, in a taller and heavier body. The figures carry across; how it feels does not, because of the weight and the ride height.

Should the gearbox be tuned as well?

Worth it, particularly on the diesels where the gain is mostly torque. The ZF 8HP has its own limiter which can clip it, and tuning the box raises the limiter and sharpens the shifts at the same time.

What about the DPF and AdBlue on the diesels?

They stay in place. Removing emissions equipment makes a car illegal on the road and fails its MOT. If yours has a fault we diagnose and repair it first, then the remap goes on a healthy car.

How long does it take?

About two hours through the diagnostic port including a road test, and your original file is kept so it can be put back to standard whenever you want.
