Design & Looks
Even five years later the 911 still looks fresh. Its classic silhouette, round headlights, and sloping roofline are instantly recognizable. Porsche kept the interior simple yet luxurious – leather seats, a driver‑focused cockpit, and a digital instrument cluster that feels modern without being flashy.
Performance & Mileage
The 2021 model ships with a 3.0‑liter twin‑turbo flat‑six that makes 379 hp (Carrera S) or 443 hp (Carrera GTS). Acceleration from 0‑60 mph is under 4 seconds for the higher‑output versions. Real‑world fuel economy settles around 20 mpg combined, which is respectable for a sports car of this caliber.
- Engine: 3.0 L twin‑turbo flat‑six
- Combined mileage: ~20 mpg
- 0‑60 mph: 3.8–4.2 seconds
- Top speed: 190–197 mph
Price & Rivals
When it debuted, the base Carrera started at $101,200. After five years the average resale price is about $70,000, a depreciation of roughly 30%. That puts it below rivals like the BMW M4 (about 35% depreciation) and the Audi RS5 (around 33%).
Buying a five‑year‑old 911 gives you most of the performance and styling at a fraction of the new‑car price, but you still pay a premium compared with non‑German sports cars.
