2025 Audi SQ5 And S5 Avants Get A Shakedown In Colorado’s Mountains

–>

Colorado is a mecca for car manufacturers looking to test new vehicles thanks to its heat and high altitude and most recently, Audi was filmed testing a trio of prototypes. But just what models are we looking at?

This clip comes from the crew at TFLnow and each of the three Audi models is clad in black and white camouflage to hide their identity. However, Audi has failed to hide the quad oval-shaped tailpipes visible on each of the three prototypes, indicating that these are all ‘S’ performance models.

The first is an SUV and looks very much like the 2025 Audi SQ5. Audi sells the current SQ5 with both a twin-turbocharged 3.0-liter six-cylinder petrol and a 3.0-liter twin-turbocharged diesel six-cylinder depending on the market. U.S. models are sold exclusively with the petrol engine and rated at 349 hp and 369 lb-ft (500 Nm) of torque, allowing them to hit 60 mph (96 km/h) in an impressive 4.7 seconds and a 155 mph (250 km/h) top speed.

CarScoops published a series of spy shots of the 2025 SQ5 last month. These photos revealed that a host of design changes will be made to it, including the fitment of new LED headlights and taillights. Audi’s designers also look to have crafted a new grille for the punchy SUV and have also made a series of changes to the cabin.

Then we have the other two prototypes. Both are estates, or Avant models in Audi lingo, and also have quad tailpipes. We suspect that these are prototypes for the upcoming S5 Avant.

For those that don’t know, Audi has changed its naming scheme, meaning EVs will have even numbers and ICE models will have odd numbers. As such, the new Audi A5 and S5 will actually serve as the replacement for the Audi A4 and S4. With this in mind, the new S5 Avant will probably have a similar 3.0-liter TDI mild-hybrid engine in Europe as the current S4 Avant. This engine is good for 337 hp and 516 lb-ft (700 Nm) of torque.
