2025 Porsche 911 Summary

The icon is electric. Well, kind of.

This is the new Porsche 911 Carrera GTS, which ushers in a facelift for the brand’s most famous model — and it’s one that introduces a pretty major change.

That faint whistling you hear is most likely the distant wails of the Porsche purists, because this new 911 is now a hybrid.

Yes, the Carrera GTS features Porsche’s clever T-Hybrid engine, which is the brand’s take on electrifying the world’s most famous sports car.

It’s faster than the model it replaces, but it also fundamentally alters the formula that has made the 911 the world’s most iconic sports car.

The question is, does it alter it for the better?

The more things change, the more they stay the same. The t-hybrid might be an entirely new propulsion system for the 911, but the net result is unchanged – power, poise and performance on tap.

Verdict

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).
