The Alfa Romeo Giulia Thread

Test figures: Alfa Romeo Giulia Quadrifoglio

We put the updated Alfa Romeo Giulia Quadrifoglio through its paces on our test strip to find out how it performs in the acceleration and braking stakes.

The Alfa Romeo Giulia Quadrifoglio recently took part in the 16th Simola Hillclimb, where it recorded a best time of of 48.73 seconds in the King of the Hill run with driver Art Denisov behind the wheel. Now, we’ve strapped our test equipment to this example to find out how it fares in our stringent acceleration and braking tests…despite running on very well-used tyres.

The pinnacle Giulia employs a 2.9-litre twin-turbo V6 engine producing 375 kW and 600 N.m, the former and latter available from 6 500 and 2 500 r/min, respectively. An engine partly developed by engineers at Ferrari, it revs to a 7 000 r/min redline – the soundtrack provided by an Akropovič exhaust system. The Giulia Quadrifoglio is equipped with an eight-speed automatic transmission, which delivers power exclusively to the rear wheels.

Alfa Romeo Giulia Quadrifoglio acceleration

On the day, the Giulia Quadrifoglio recorded a 0-100 km/h sprint time of 4.70 seconds on our standardised test strip. (Alfa Romeo claims 3.9 seconds.) It is worth noting that, compared to our latest figure, the pre-facelifted model we tested in 2017 was 0.75 seconds quicker to the three-figure marker, with the team noting it had “no trouble putting its power down”.

The Italian performance sedan covered the quarter mile in 12.94 seconds, at a speed of 194.70 km/h, before reaching the 1 km marker 9.59 seconds later, at 249.93 km/h. In the overtaking acceleration stakes, the Alfa Romeo sprinted between the 80-100, 100-120 and 120-140 km/h increments in 0.90, 1.14 and 1.32 seconds, respectively.

2027 Alfa Romeo Giulia and Stelvio gain new tech and styling

Alfa Romeo remains committed to the Giulia and Stelvio, with the Italian automaker issuing key refinements to the former and latter for the 2027 model year. This includes subtle exterior updates, enhanced onboard technology, and interior quality upgrades.

Alfa Romeo has stressed the Giulia and Stelvio will continue to express its core identity. Despite modest global sales since their initial launch, these models endure as compelling alternatives to the likes of the BMW 3 Series and Mercedes-Benz C-Class, and X3 and GLC. For 2027, the Italian brand has streamlined the lineup into four distinct trims: Sprint, Veloce, Edizione Luna Rossa, and Quadrifoglio.

Powertrain availability varies by region. The European market retains a 2.2-litre, four-cylinder turbodiesel. Offers in two states of tune, the oil-burner can be had with either a rear- or all-wheel drivetrain, paired with an eight-speed automatic transmission. Select global markets receive a 2.0-litre, four-cylinder turbocharged petrol engine, which sends 206 kW to the rear wheels via the same eight-speed self-shifter.

The Quadrifoglio continue to spearhead the range. The apex models in the Giulia and Stelvio lineups employ a 2.9-litre twin-turbocharged V6 developing 382 kW. In the sedan, power is exclusively delivered to the rear wheels, while the Stelvio features Alfa Romeo’s Q4 all-wheel-drive system. The automaker has sharpened handling dynamics via Chassis Domain Control, active suspension, and a mechanical self-locking differential. The extensive use of carbon-fibre components has reduced kerb weight. The Stelvio Quadrifoglio upgrades to 21-inch alloy wheels as standard.
