The Porka 910 is a racecar featured in Grand Theft Auto: London 1961.
Like various cars bearing the "Porka" name, the Porka 910 is clearly a factory-built motorsport car based on a Porsche, specifically, a Porsche 910; this is yet another anachronism in the game, as the Porsche 910 did not debut until 1966, five years after GTA London 1961's setting. Being a racing car, the Porka 910 may also come with a single or double-colour racing stripes, as well as occasional but unidentified markings on the car's doors.
The Porka 910's performance is considerably good, with excellent top speed, acceleration, braking and handling. The car also has a 2% more vehicle health than usual, and may be exported for a base payment of £1,200 if delivered in mint condition.
