Ben Affleck now has a car suitable for his newly-formed Batman muscles ... a 2015 Dodge Challenger Hellcat.
Ben was tooling around in his newest acquisition Tuesday near the family home in Pacific Palisades. It's a rare ride ... only 2,000 were manufactured.
The car goes for $90k and it has plenty of power ... 707 horsepower.
One final fun fact ... Ben bought the car over the phone. That's Affleck money.
