It marks the first time Bandai Namco has managed that feat since Ridge Racer Type 4 way back in 1999.
It managed to hold off a push from standalone expansion Wolfenstein: The Old Blood, which enters the chart in second, despite having its digital edition being released on the 5th May. The PS4 performed very well in the launch, with it accounting for a 67% share of the overall sales, compared to 27% on the Xbox One, according to Chart Track.
Grand Theft Auto V may have dropped down one place to third, but the game has now passed 5 million total sales in the UK.
Mortal Kombat X is also down one place, into fourth this week. Just below it is another new entry, with the PS4 exclusive Final Fantasy X / X-2 HD Remaster, with a respectable showing in the chart.
Despite dropping down the charts we have two mainstays in the Top 10 still going strong, with FIFA 15 down to sixth and Call of Duty: Advanced Warfare in seventh this week.
Dying Light tumbles three places to eighth, likewise with Battlefield: Hardline down to 10th.
The other game to sit in the Top 10 is Destiny, which climbs one place to ninth.
The UK All Formats Chart Top 10 (Week ending 16th May 2015) is as follows:
1. (-) Project: CARS
2. (N) Wolfenstein: The Old Blood
3. (2) Grand Theft Auto V
4. (3) Mortal Kombat X
5. (N) Final Fantasy X/X-2 HD Remaster
6. (4) FIFA 15
7. (6) Call of Duty: Advanced Warfare
8. (5) Dying Light
9. (10) Destiny
10. (7) Battlefield: Hardline

Next week should almost certainly see The Witcher 3: Wild Hunt claim the top spot, considering it has already clocked in 1 million pre-orders. With the release of the latest expansion for Destiny, it would not be too surprising to see Destiny make a move up the chart.
