The verdict

What's good

AMG-sourced twin-turbo V8 sounds distinctly Aston rather than generic Mercedes
Fabric roof stows quickly without compromising trunk space meaningfully
Ride in GT mode is genuinely supple for a British sports car
Hand-finished interior craftsmanship stands out against German rivals at similar price

What's not

Aston Martin dealer network is sparse outside major metro areas
Ownership reliability costs can be unpredictable over a three-year period
Infotainment system lags behind rivals in responsiveness and feature depth
Resale depreciation is steeper than comparable Porsche 911 or AMG SL

The engine

4.0L Twin-Turbo V8

Aston's 4.0-liter twin-turbo V8 trades the old naturally-aspirated bellow for savage, hot-vee turbocharged thrust — re-tuned with bespoke intake, exhaust and software to sound and feel unmistakably Aston.

Sourced from Mercedes-AMG in Affalterbach as part of a technical partnership, then re-engineered by Aston Martin to suit the lighter, more agile character of cars like the Vantage and DB12.

The block comes from AMG but Aston fits its own intake, exhaust and calibration to change its voice.
The same basic engine powers the Mercedes-AMG GT, tuned very differently.
