Gran Turismo 7 releases its largest update yet ever since the game was first released on March 4th 2022, and there a lot of cool new things added in Update 1.40. To name just a few of them:

  • 7 new cars have been added to the game.
    • Dodge Charger R/T 426 Hemi ' 68
    • Dodge Challenger SRT Demon '18
    • Lexus LFA '10
    • Mercedes-Benz 190 E 2.5-16 Evolution II '91
    • Nismo 400R '95
      • This is the very first game to use the '95 model. Every previous game up to this point has used the '96 model.
    • Porsche 911 GT3 RS (992) '22
    • Tesla Model 3 Performance '23
  • New Snow Track - Lake Louise
    • Contains 3 different layouts: Long Track, Short Track, and Tri-Oval. Each layout can also be run in reverse for a total of 6 new courses.
    • This is the first new snow track to the franchise ever since Gran Turismo 5's version of Chamonix back in 2010. Gran Turismo Sport had Snow Tires available to buy, although they were functionally useless due to the lack of any snow tracks in that game.
  • Master License
    • After you clear all the Normal Licenses, you unlock the Master License which contains a whopping 50 new tests to complete. It's not clear if they are required for anything other than bragging rights.
  • Two new Scapes locations
    • Now you can take a picture of your car inside the game company's office building!
  • Loads more! I couldn't possibly write all of this out here.
