Let me add more details from the article. It's translated by Google, so keep in mind there could be errors.
And if it reads too negative, it's because those are the things that usually stand out the most to me.
In order to get a car for the test, Sport Auto France had to agree to only use SP100 fuel (only available in Italy and Switzerland) instead of 98 octane they put in every other car! The magazine wasn't happy, but Dallara was adamant on this.
Engine & Transmission
The transmission is a bit too slow (there is a software update in the works that will improve shift speed).
The engine could be more responsive and offer more pleasant sound.
Above 5,500 rpm the engine runs out of steam a little.
Interior
They had to change padding of the seat for thinner version to fit the test driver.
The brake pedal feel isn't ideal (too much travel).
The vision out of the canopy is most excellent.
There is noticeable amount of tire roll and wind noise in the cabin (probably why there's no radio onboard).
Road handling
Unassisted steering is perfect. Calm in the center, yet sharp in turns.
Tractions is very good and the handling is predictable. The modest amount of camber works well on normal b-roads.
Track test
The car has slight understeering tendency. The rear end is very planted.
According to the author, there is a lot more potential in the car to be unlocked with better suspension setup. The tires were worn on the outside, meaning there wasn't enough negative camber, limiting lateral grip. Apparently it's a concession made by Dallara to have more approachable handling for the average customer.
Dallara team adjusted the ride height and the damping for the track test, which made the car bottom out at high speed and caused damage to the carbon diffuser.
Their time on track was cut short by an engine related mechanical issue, not repairable on site. Luckily the author had already set his best lap time, despite the less than ideal camber setup.
Acceleration
Even with launch control enabled, you have to modulate the throttle in first gear to get the quickest acceleration results.
Here's some of the reasons listed as to why Sport Auto FR fell short of manuf. 0-100 kph claim of 3.3s, with their own result of 3.8s:
- subpar tarmac surface grip of the test location in Mortenfontaine
- Dallara team admits the factory driver was a flyweight
- factory car was stripped of any optional equipment (canopy, AC)
- factory car was equipped with 17"/18" wheels (IR8 Tribute edition has 18"/19")
- factory measured the car with the least amount of fuel necessary
Dyno results
(all results adjusted for drivetrain losses)
The car didn't run SP100 fuel on the dyno.
The maximum torque was suspiciously high:
581 Nm at 3,250 rpm (advertised 500 Nm at 3,000 rpm). Despite a laptop being plugged in the car during the dyno run, Dallara assured them the ECU was running stock maps and was just data logging. They explain the results by saying the conditions were ideal.
Max power was
399.3 PS at 5,500 rpm (advertised 400 PS at 6,200 rpm).
The €373k price includes €60k of "penalty", which I assume is local tax. Base price is €255,000, options: €58k
It's cool to finally know how much a coupe version weights. Here's compiled data:
| publication | configuration | 0-100 | 0-200 | weight w/ 38kg of fuel |
|---|
| factory claim | Barchetta | 3.25 | 11.3 | 855 DRY! MT |
| Quattroruote | AT Barchetta +wing | 3.3 | 11.7 | 944 (w/o QR balast) |
| Motorsport FR | AT Barchetta +wing | 3.3 | 11.3 | 951 |
| sport auto FR | AT Coupe +wing | 3.8 | 12.8 | 1,027.5 |
Motorsport FR acceleration results suspiciously identical to factory claims. Did they even clock it with GPS?
