The Alfa Romeo Giulia Quadrifoglio is a Cheat

The Alfa Giulia Quadrifoglio is so fast that it rips to 60 MPH from a stand still in blistering 3.8 seconds. Yes, yes, Tesla P something’something D. Moving on. Keep the right foot down and the Alfa crosses the quarter mile in about 12 seconds flat at 120 MPH, too. But nobody cares about drag racing. Let’s talk about lap times.

This is when panties start getting wet. Looking at some of the quicker Nurburgring laps we have the BMW E92 M3 GTS at 7’48”. A little quicker is the Porsche 911 GT3, 997.2, at 7’41”. The Nissan GTR Spec-V did a 7’34”. The Alfa Romeo Giulia Quadrifoglio, piloted by Alfa Romeo and Maserati test driver, Fabio Francia, lapped a 7’39” and then supposedly followed up with a 7’32” with the automatic transmission. That’s faster than the Audi R8 GT, Lexus LF-A and the Lamborghini Gallardo LP 570-4 Superleggera. You can watch the video here.

If you wanted a car capable of besting the Giulia Quadrifoglio around the Green Hell, you could do it in a million dollar Porsche Carrera GT. If that’s not in your reach, try for the McLaren MP4-12C or the latest Porsche 911 GT3 RS. None of which are well suited for a trip to Kroger. Or Shoppers, if that’s your bag.

“What is this SORCERY”, you might ask? Rubber.

It’s all in the tires. Repeat after me. It. Is. All. In. The. Tires.

The secret weapon was to rock a tire specifically designed for the car by Pirelli, knowing damn well they were pulling one over on their customers.

Alfa Romeo worked closely with Pirelli to design competition tires for the Giulia Quadrifoglio.

Alfa knew what they were doing. They needed the Giulia Quadrifoglio to light heads on fire. The secret weapon was to rock a tire specifically designed for the car by Pirelli, knowing damn well they were pulling one over on their customers. And not just any tire. They needed a cheater tire. Sure, it’s there printed right on the spec sheet but most buyers don’t know the wiser.

Giving credit where due, most automotive outlets will state that it has fancy tires but they do not clearly express just how important they are. By the time the reader skips to the performance and test results, the thought had passed.

Pirelli designed the P Zero Corsa AR Asimmetrico exclusively for this car. See that “AR” designation in the name. Guess what that stands for.

Let’s use Tire Rack’s tire tests for study. Many tires they test against groups of other similar tires. They test things like lateral Gs, road noise, steering response and dry and wet lap times. There are performance summer tires that lap the course in 31 seconds and there are performance summer tires that lap it in 29. So if the gap is 2 seconds for every 31 seconds on course, on the ‘Ring that would slow a 7:30 second car to over 8 minutes.

And that is the potential difference just between similar performance street tires. The gap could and would likely grow greater if the comparison was with the Pirelli P Zero Corsa AR and a tire that comes on one of the Giulia Quadrifoglio’s so-called competitors, such as the BMW M3 Competition Package or Cadillac ATS-V.

So while you Giulia owners and fanboys might argue it’s a “street tire” because it comes on a car that’s driven on public highways, they’re wrong. It’s not a street tire. What the Pirelli P Zero Corsa AR Asimmetrico is, is a street legal race tire with a 60 UTQG rating. You can read more on UTQG here.

The P Zero Corsa AR Asimmetrico comes with just 6/32nds of tread depth. This reduces squirm in the tread blocks for better response and heats up the tire quicker. Tire Rack labels it “Streetable Track and Competition tire” followed with a WARNING. “P Zero Corsa System radials meet DOT requirements, however they are not recommended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions.”

That doesn’t sound like a tire I’d want on any car I would consider taking on a road trip.

Before you call me a hater of some sort, let me clear this up by saying I would gladly purchase an Alfa Romeo Giulia Quadrifoglio. I simply can’t afford one. Maybe second hand down the road if they prove reliable, and after my E92 M3 is paid off (and begins to bore me).

Alfa Romeo Giulia Quadrifoglio power slide
The torque of the 2.9 liter twin turbo engine puts even the stickiest of tires to work when mounted on a 3,700 lb sedan.

I’m going to take this another step. If you’re at all familiar with time trials, or “time attacks” as the kids call them. I call them that too. Then you might have known that most all venues restrict street cars to a specific width (285 is typical for RWD) and 200 UTQG rated tires or higher. Why?

BECAUSE IT’S A GOD DAMN STREET CAR. And the Alfa Romeo Giulia Quadrifoglio is not a fucking race car. It’s a street car with an automatic transmission, navigation, comfortable power seats and back seats for children or your in-laws (not recommended).

Just watch. Soon Giulia owners will be out replacing their tires with actual street tires because they want to drive a sport sedan every day like a normal human being. And suddenly the car doesn’t handle the same.

Earlier this week Motor Trend placed the Alfa Romeo Giulia Quadrifoglio against the BMW M3 Competition Package at Thunderhill Raceway. Thunderhill is a 2 mile road course with some great corners and high speeds that should have highlighted the Giulia Quadrifoglio and it’s cheater tires. Only the Alfa didn’t win. But in all fairness, neither did the BMW M3. Both turned a 1:23.89.

What’s interesting is that the BMW M3 Competition Package uses 300 UTQG rated Michelin Pilot Super Sport tires and has a 40 horsepower deficit. So, no, the Alfa Romeo Giulia Quadrifoglio isn’t king sport sedan. Fuck you, Alfa.

  1. As a potential buyer, I would want multiple tire options. Magazines could (would likely) still test it using the higher spec rubber, as part of a comp package or whatever Alfa would call it, but owners would have tires that actually work in the rain and take longer to wear. If they so choose.

    As far as cheating, Alfa sold the car wearing a tire, the car got tested using that tire. That ain’t cheatin. Whether owners will get pissed over time, we’ll see, but any car company could do the same thing. If they so choose.

  2. Tires really are everything. My BRZ, on its stock tires, was the opposite extreme. Narrow, slippery tires made it slide all over the place – a plus for the drift crowd, but a minus for me. They seriously held the car back from reaching its potential. If they’d given it wider, grippier rubber it would’ve done much better on lap times and in the comparisons. Might even have beat the Miata in the 1/4 mile.

    On the flip side, the new WRX comes on Dunlop Sport Maxx tires. Summer tires, and the cars are quite popular in the snow belt. That definitely helps its warm weather performance a bit and boosts the numbers, but holds it back when conditions get slippery – conditions that the WRX was made to conquer.

  3. That’s quite the unique review…your language made me laugh too…not sure I agree with your insights.,I still respect them…between the BMW and the Alfa…I’ll take the Alfa…better yet as a family sedan I’ve chosen the tesla model 3 with awd and performance mode….hell its my family transport….for track or spirited street driving,….I’ll hope in my z51 m6 corvette weighing in at 3200 lbs and 450 hp..(lightly modded)

  4. Your analysis is wrong, P Zero Corsa are high performance tyres but not semi-slicks like the Pilot Sport Cup 2 used by BMW on M4 GTS, P Zero Corsa should be compared to Michelin Pilot Super Sport, and the treadwear you claim about P Zero Corsa is false cause P Zero Corsa is a dual compound tyre, not a single compound tyre, so it’s true that some parts of the tyre have an extreme sticky compound like the one used on the semi-slick Pirelli Trofeo R, but in other parts of the tyre they use another compound with high treadwear to improve durability. At last as Giulia Quadrifoglio was developed in collaboration with Pirelli and the P Zero Corsa tyres, the M3/M4/M3 ZCP/M4 ZCP was developed in collaboration with Michelin and the Pilot Super Sport tyres and m4 GTS with the semi-slick Pilot Sport Cup 2 tyres.

    1. The factory tires have a 60 UTQG rating. You’re telling me that’s on part with Michelin Pilot Super Sports? Cmon man.

  5. Cheat? Not really. The Pirelli Corsa AR is the tire that comes with the Alfa QV as stock. Other manufacturers are free to work with a tire company and develop their own tire as well. And, by the way, most QV buyers are fully aware of the strengths and limits of the Corsas. Also, you can’t use Tire Rack’s lap times and translate that to the Nurburgring times. The Ring is a totally different track, with significantly longer straights where tire grip has no bearing on speed.

  6. Y’all should watch the youtube video of this Alfa vs Mercedes A45 AMG. The latter has AWD and 130 horsepower disadvantage. It blew away the Italian Stallion like the prime Randy Moss ran past Safety guys. So much praise given to this overhyped Alfa and yet in drag race it was humiliated.

  7. Awesome write up. I know. It sucks as a BMW guy. Get some stiffer springs for the F80. I’m a BMW guy for 25 years and still am. The Q walks the M3 in every category but reliability I’m afraid. Get rid of your Super Sports and your suspension on the M3. That’s a great starting point. Looking for a track car? Buy a 911 or do more mods to the F80. Spend $8-10k on the F80 and it will compete with the Q. I’ve done it. But barely. Throw a set of Sport Cup 2s on the Alfa and it’s still a stallion. Yes. Tires were very smart. That is the kind of tire that car should have. 300 Treadwear is slick. Super Sports suck. The M3 is held back immensely by them. The Q is so good it’s annoying. It’s so Italian, it’s annoying. The suspension is so dialed in, it’s annoying. I’ve been driving on track for 20 years. The Alfa is a breakthrough. Ouch to us BMW guys. My favorite car is still an E30 M3 though. Although the early ‘90s Q’s are pretty hot. Not an E30 though. I feel for you. But once you drive the Q, the F80 will have a for sale sign in it. It’s just a sloppy mess. The spring rates are 1/3 what they should be. The dampeners are not calibrated right. Those wanting a more “daily” tire shouldn’t by the Q. They should by a Ti Sport. This is a track car. It’s not a daily. There again I’m the 1% person that will drive the car 9/10ths and Best the snot out of it.

  8. Who published this article? What a horrible read. Some points raised were valid but why all the harsh language? So bitter.

    Also Alfa can put what ever tyres they want on their car and develop them as they see fit, what’s your problem? It’s not like the Michelin Pilot Sport Cup 2 is really a tyre you could use every day either and plenty of manufacturers are putting them on cars to get impressive lap times.

    Also none of these cars are race cars, so why even bring this up?

    What a sad bitter person.
