2020 Alfa Romeo Stelvio Quadrifoglio exhaust is just as good as you hoped

Alfa Romeos, especially the fast ones, are car enthusiast darlings. As such, you likely already know that the 2020 Alfa Romeo Stelvio Quadrifoglio has a Ferrari-derived twin-turbo V6 making 505 horsepower and 443 pound-feet of torque. What you may not know for sure is how it sounds. And if you watch the video above, you'll know positively that it sounds excellent. Most of the video features the Alfa in Dynamic or Race modes, which open up the exhaust and make the shifts faster and aggressive, among other things such as stiffening the suspension. In these modes, the Alfa growls, howls and everything in-between. It's not a flawless performance, as there are times you get a bit of V6 drone, but when its right, its pipes sound amazing Fortunately for anyone with easily agitated neighbors, or buyers who want to take the Alfa on long drives, it quiets right down in its normal and eco modes. It also starts in the normal mode by default, so you won't wake anyone up if you have to drive off late at night or early in the morning. Certainly in the sound department, the Stelvio Quadrifoglio is a well-rounded performer. Related Video:

Alfa Romeo's Giulia Quadrifoglio gets the GTA treatment

Alfa Romeo will celebrate 110 years of building some of the world's most emotional driving machines with a brand-new Giulia Quadrifoglio GTA. GTA, which stands for "Gran Turismo Alleggerita," is a throwback to the 1965 Giulia Sprint GT, which first got the treatment. The new GTA and GTAm will elevate the Giulia's already driver-friendly formula to a whole new level.  If the plain-Jane Giulia Quadrifoglio is a BMW M3 or Mercedes-AMG C63 competitor, the GTA is your Competition or "S" variant, respectively. It boasts more power, less weight, enhanced aero, a revised suspension, and a reworked chassis and interior designed to keep the driver in place and focused on one task and one task alone: driving fast.  The wick on the GTA's 2.9-liter twin-turbocharged V6 has been turned up a bit, resulting in a new peak rating of 540 horsepower (up 30 from the base car). To reduce weight, Alfa replaced a host of exterior panels with carbon fiber equivalents. The carbon treatment extends to some other components, such as a the drive shaft. Alfa says the net reduction works out to 220 pounds.  Outside, the aero has been completely revised with technical know-how provided by Sauber Engineering (of F1 renown). It also boasts 20-inch center-locking wheels and a titanium exhaust system. Alfa replaced many of the suspension bushings, the shocks and the springs with performance-friendly hardware. The GTAm pushes the formula even farther. We hesitate to compare a sport sedan to a GT Coupe, but the relationship between GTA and GTAm is quite similar to that between the Porsche 911 GT3 and GT3 RS. Both are fundamentally the same car, but the latter compromises a great deal more of its daily drivability for the sake of improving its on-track feel and performance.  With the GTAm, this included a set of carbon-backed front bucket seats with six-point harnesses, Lexan window inserts for the side and rear windows, and a rear seat delete. In place of the rear bench, you get a harness bar attached to a structural roll hoop, plus a handy little cubby for storing your custom Bell helmet in Alfa's GTA livery (which comes with the car, as well as an Alpinestars race suit, gloves and shoes, and a personalized Goodwool car cover). Checking in at just 3,350 pounds, the GTAm boasts a power-to-weight ratio of 6.2 pounds per horsepower, which Alfa says is the best in the class, enabling a 0-60 run in just 3.6 seconds.

Alfa Romeo Giulia runs the Nurburgring

Usually when spying a pre-production car, the goal is to figure out what it looks like underneath the camouflage. However, that's not a concern with his video of a heavily concealed Alfa Romeo Giulia Quadrifoglio because the design was already fully revealed. Instead, this is an opportunity to listen to the upcoming sports sedan lapping the Nurburgring. For a vehicle with just 2.5 years of development by only 11 people, the Giulia certainly makes all the right noises. The twin-turbocharged 3.0-liter V6 engine has a growling note as the sedan speeds away, and there's no audible turbo whistle – at least in this clip. The sound is angry but still somewhat subdued for a mill making 510 horsepower. The test driver here is really pushing things, and the tires are squealing through practically every corner. The Alfa's rear end even steps out a little a few times. The Giulia is slated to arrive in the US in the first half of 2016. In the meantime, we look forward to seeing the sedan again at the Frankfurt Motor Show in September, where some additional powertrains are rumored to debut. Related Video:
