It's time to take a step back from today's contemporary racing cars (well, not completely) and get into a bit of the old school, as Microsoft and Turn 10 Studios have announced that they are releasing a special Pennzoil Car Pack for its racing behemoth Forza MotorSport 4.

The pack, which will go for 560 Microsoft points ($7), includes the following vehicles…

2013 Viper #91 SRT Motorsport GTS-R

2013 Viper #93 SRT Motorsport GTS-R

1968 Alfa Romeo 33 Stradale

1960 Aston Martin DB4 GT Zagato

1958 Austin-Healey Sprite MKI

1953 Chevrolet Corvette

1965 MG MGB GT

1955 Mercedes-Benz 300 SLR

1967 Volkswagen Karmann Ghia

1983 GMC Vandura G-1500

2011 Citroën DS4

In addition, the pack will also let you take on new Community Monthly Rivals mode events, including one dedicated to the Pennzoil-supported Vipers, the 2013 models.  So, see, a little new-school doesn't hurt after all.

No release date has been given, but we expect the pack to drop in the next couple of weeks.  Time to hit the road again!
