The month of August - which also sees Japan's Obon national festival take place (August 13-15) as well as the Mountain Day national holiday (August 11) - has only been skipped once for an update, and that was in 2024. Aside from December (twice), no month has been passed over more than once, but January, April, June, July, August, September and October have all been missed once apiece.
However, we are also on the current joint longest run of months with updates since January-May 2024, at three - tied with January-March 2025...
The two previous August updates have contained three and four cars respectively. They've also both contained American cars - the Pontiac GTO The Judge and the Chevrolet Corvette C1. Only November beats it, separately adding the Sierra RS500, Tesla 3, and Escort Cosworth in its three updates, while May has added three American cars separately in four different updates (only 2024 had none).
We've had 31 updates with 115 cars so far, at an average (mean) of 3.7 cars per update. 19 of 31 updates have contained three cars. Three cars thus remains likeliest, with four also possible.
Road cars overwhelmingly outnumber race and tuned - in fact by triple the combined count. The average remains 2.8 cars per update, to 0.7 and 0.2 for race and tuned respectively. You should expect three road : one race for a four-car update (though this has only happened twice in five instances) or two road : one race for a three-car update (seven times from 19).
Asia and Europe are about equal in terms of car origins, though the all-Asia update last time out gave the advantage to Asia - 52:49 - after being equal. Only 14 American cars have been added, and four were SEMA cars and two Ford of Europe cars... We've had six all-one-region updates, and five of those have come since 1.52/October 2024 (the very first one was the other). Four (three since October) were all-Asia, two were all-Europe; there's never been an all-American update.
We're now in the sixth occurrence of (n)-0-0 for updates with American cars. Four of those became (n)-0-0-0-1, with the exception being 1.20-1.26 (and that was the Sierra RS500...).
Brand Central cars outnumber Legends and Used-only by 3:1 each, at 2.3/update compared to 0.7 apiece for the others.
All-new cars are almost triple returning cars (even where returnees include very similar vehicles but a different year or spec-tweak) at 2.7:1.0 but returning cars had a huge boost in a run from April 2023 to October 2024 and have recently tanked - three in seven updates since and eight in 11 updates prior to this period. Excluding that bump, it's almost 5:1 in favour of all-new cars (54:11, in 18 updates).
Four of the last five updates have been among the nine least-expensive in terms of credits required to buy the cars in the game's history. The last one, 1.61, was the exception, at the 13th priciest and the one preceding the run was the 19th. Of the ten sub-million updates, four have arrived this year and five since October 2024. Then again, the most expensive and one of only two eight-figure updates was in November 2024.
