Aston Martin Caught Testing Its Porsche 911 GT3 Rival: Video

• Aston Martin is developing a hardcore Vantage aimed squarely at the Porsche 911 GT3.
• The Vantage could pack more than 700 horsepower from its twin-turbo V8.
• A huge rear wing, aggressive splitter, vented fenders, and a revised diffuser point to a track-focused Vantage.

The closest thing Aston Martin has ever had to a true Porsche 911 rival is the latest Vantage. Not only does it look great, but it has the dynamics to keep up with Stuttgart’s finest. But if Aston really wants a 911 rival, it needs something that can keep up with Porsche’s most potent model: the GT3.
