September 15 gives Project Motor Racing a paid DLC date and a free re-entry hook
The Project Motor Racing V8 Power Pack is now dated for September 15, 2026, with publisher GIANTS Software and developer Straight4 Studios confirming a paid content drop built around nine V8 race cars and Michelin Raceway Road Atlanta. The announcement, distributed through Games Press and covered by outlets including Operation Sports, IGN, BoxThisLap, and OverTake, fixes the pack’s timing after it had previously sat on the game’s Year 1 roadmap for Q3 2026, according to BoxThisLap.
The immediate tension for sim racers is that September is not only a paid-DLC month. GIANTS Software and Straight4 also say the Lamborghini Temerario will launch for free in September after making its first playable public appearance at gamescom 2026 in Cologne. BoxThisLap specifically notes that the Temerario is separate from the paid V8 Power Pack DLC, which matters for anyone deciding whether to reinstall, test recent updates, or wait on pricing before buying into another pack.
That makes Project Motor Racing September 15 a clearer decision point than a normal car pack release. Returning players are being offered a paid American and Australian V8-focused expansion on a fixed date, plus a no-cost Lamborghini in the same month. One asks for a purchase or Season Pass ownership; the other gives lapsed players a reason to check the current state of the sim without paying first.
The V8 Power Pack contents are split by era, not simply by brand
According to the publisher announcement shared through Games Press, the Project Motor Racing V8 Power Pack adds three classes: V8 Evo, USV8, and Historic USV8. V8 Evo contains the 2023 Ford Mustang AU and 2023 Chevrolet Camaro AU, representing modern Australian-style touring car machinery. Operation Sports describes these as rear-wheel-drive cars with significant power, large brakes, and enough aerodynamic support for faster sections while still being suited to close racing.
USV8 shifts the pack toward modern American TA2-style machinery with the 2022 Dodge Challenger TA/2, 2022 Ford Mustang TA/2, and 2022 Camaro TA/2. IGN and Games Press both list those three models as part of the pack. For sim racers, that class structure suggests a useful middle ground: contemporary tube-frame muscle with comparable layouts, likely better for packed multiclass-style club racing than for gentle solo lapping.
Historic USV8 is the most handling-sensitive part of the pack. Games Press lists the 1970 Ford Mustang Boss 302 TA, 1970 Plymouth Barracuda TA, 1970 AMC Javelin TA, and 1968 Camaro TA Z28. Operation Sports’ write-up differs on the Camaro, naming a 1969 Chevrolet Camaro Z/28 TA instead. Because the publisher press release, IGN, BoxThisLap, and Happy Gamer all point to a 1968 Camaro variant, the safest reading is that 1968 is the officially supported listing unless Straight4 publishes a correction elsewhere.
Operation Sports frames the historic cars as requiring more patience than the newer machinery, citing body roll, mechanical grip, and throttle control as defining traits. That is the right expectation to set. Older Trans-Am-style cars usually reward progressive steering and throttle application rather than late, aggressive inputs. If Straight4’s physics and tire model communicate weight transfer cleanly, this class could become the pack’s most demanding test of car control.
Road Atlanta is the right circuit choice for this pack’s strengths and risks
Michelin Raceway Road Atlanta is included with the pack, and the official announcement describes it as a scanned U.S. circuit. BoxThisLap and OverTake call it laser-scanned, while IGN describes it as fully scanned. Across the source material, the consistent point is that Road Atlanta is intended to arrive as a detailed representation rather than a generic fictional stand-in.
The circuit selection fits the V8 Power Pack’s structure because Road Atlanta exposes several different weaknesses in a racing sim. Its fast esses test aero balance and suspension response. Its blind crests punish vague steering feedback. Its heavy braking zones reveal whether ABS-free or low-aid cars remain stable as weight moves forward. Operation Sports highlights the track’s fast esses, blind crests, braking zones, and elevation changes as characteristics that should suit the nine-car pack.
For V8 Evo and USV8 cars, Road Atlanta should make braking performance and traction off slower corners central to lap time. For Historic USV8, the same layout becomes a patience test: carry too much speed over a crest or lean too hard on throttle while the car is still loaded, and the lap should unravel quickly. That makes the track a useful proving ground for players returning to Project Motor Racing after earlier updates, because it compresses many physics questions into one venue.
The free Lamborghini Temerario is separate from the DLC, and that changes the return calculation
GIANTS Software and Straight4 are presenting the Lamborghini Temerario at gamescom 2026, where Games Press says it is playable on the showfloor in hall 6 before launching for free in September for Project Motor Racing. The publisher announcement calls this the car’s first playable public appearance. It also says the Porsche 718 Cayman GT4 Clubsport will headline hot-lap competitions at the stand, with racing rigs featuring rebuilt GT3, GT4, and LMDh content.
The important distinction is commercial. The Lamborghini Temerario is not listed as part of the V8 Power Pack. BoxThisLap explicitly states that it will arrive separately as free content, while the V8 Power Pack remains paid content and part of the Year 1 Season Pass. For players searching Project Motor Racing Lamborghini Temerario, the relevant answer is simple: it is scheduled for September, it is free, and it is being used as a public-facing showcase before the DLC date arrives.
That matters because a free car gives sim racers a lower-risk way to reassess the game. If someone stepped away after launch, or only returned for earlier free content, the Temerario can be used to test force feedback, performance, controller or wheel behavior, and online population before committing to the V8 Power Pack DLC. The September timing puts the free car and the paid pack close enough together that one can inform the other.
Pricing is still the practical unknown, especially for players outside the Season Pass
The strongest confirmed purchasing detail is that the V8 Power Pack is included in Project Motor Racing’s Year 1 Season Pass. BoxThisLap reports that the pack sits alongside the previously released Group 5 Revival, Japanese Prototypes, and GT Icons packs, with the World Endurance Pack planned for Q4 2026. OverTake also reports that pricing has not yet been announced, while BoxThisLap says standalone pricing has not been formally announced through the game’s main website.
Games Press says pre-orders for the V8 Power Pack are available on selected digital channels, but the provided source text does not include a standalone price. That leaves a split audience. Season Pass owners already know the pack is part of their paid content path. Everyone else should wait for their platform storefront to show final pricing before treating September 15 as an automatic purchase.
Platform coverage is also worth reading carefully. The publisher release states that Project Motor Racing is available for PC, PlayStation 5, and Xbox Series X|S. Happy Gamer reports that the V8 Power Pack hits PC, PS5, and Xbox Series X|S on September 15. The sources provided do not describe last-generation console versions, cross-buy terms, file size, frame-rate targets, or platform-specific performance notes for the pack.
For returning sim racers, the pack’s value depends on physics confidence as much as car count
Nine cars and a scanned Road Atlanta is a substantial themed drop, but the pack’s real value will depend on whether Project Motor Racing makes its three V8 eras feel meaningfully different. A modern Australian V8, a 2022 TA/2 car, and a late-1960s or 1970 Trans-Am machine should not ask for the same inputs at corner entry, mid-corner rotation, or throttle exit. The source material points to that separation, especially through Operation Sports’ description of the historic cars as more reliant on body movement, mechanical grip, and throttle discipline.
The recent content cadence gives September extra weight. IGN notes that July’s free Aussie Rivals pack added the 2013 Holden VF Commodore and a completely reworked 2013 Ford Falcon FG. BoxThisLap places the V8 Power Pack after several earlier Year 1 packs and before the Q4 World Endurance Pack. In other words, Straight4 is not dropping a random one-off theme here; it is extending a V8 thread that already received a free Australian-flavored update earlier in the year.
The sensible approach is different by player type. Season Pass owners should treat September 15 as a physics and content check across three related classes, with Road Atlanta as the control circuit. Players without the pass should first try the free Lamborghini Temerario when it arrives, then decide whether the V8 selection and Road Atlanta justify the standalone price once that price is visible. If your interest is historic car control, the Historic USV8 roster is the pack’s sharpest hook. If your interest is close modern tin-top racing, V8 Evo and USV8 will be the classes to watch when lobbies start forming.
