The Tommykaira ZZII was a Japanese mid-engined sports car engineered and developed by Tommykaira in 2001. Designed by Noriyuki Nishida, the ZZII was intended to be the bigger and faster version of the ZZ, but it failed to enter production and remained in the prototype stage.
Vehicle retailer Autobacs Seven bought the design shortly after it was shown and tried to market the car as the RS01.[1][2]
Specifications and design
The car is powered by a 2.7-liter twin-turbocharged RB26DETT I6 engine sourced from Nissan delivering 542 hp (404 kW; 550 PS) at 5,900 rpm.[1] The car was intended to weigh 1,000 kg (2,205 lb), mostly thanks to its ZZ-derived aluminium chassis and full carbon fiber bodywork.[3] The frame is of the same type of the ZZ - square section extruded aluminium tub, with steel subframes - but the tub was shaped as an oval instead of an arrow, by curving the walls, so the seats didn't have to be pointed inwards. The subframes were designed as crumple zones too, so that the car could be crash homologated. The design is aerodynamic and intended for lower drag coefficients and better airflow. The two distinctive roof dynamic air intakes come to shape a large NACA duct on the rear window, intended to collect more air into the intercooler.[citation needed] The power is delivered to all four wheels by a 6-speed Getrag manual transmission derived from the tenth-generation Skyline GT-R together with the ATTESA ET-S system, also making the car all-wheel drive. A custom transfer case had to be designed to allow for different diameter wheels front to rear. Autobacs estimated it to weigh 1,200 kg (2,646 lb), due to the all-wheel drive system and to the bodywork of the prototype being made of fiberglass.[citation needed] The ZZII is capable of doing 0–60 mph (0–97 km/h) in 3.1 seconds (less than 3 s according to some sources) despatching the quarter mile in 10.8 seconds at 129mph and a claimed top speed of 210 mph (338 km/h).[2][3]
Fate and potential revival
After its unveiling at the 2002 Tokyo Auto Salon, Tommykaira promised to sell the car in high volumes, with the company already having an organized delivery schedule after the show.[4] Shortly after its unveiling, however, the design was bought out by Autobacs Seven, and later renamed the car to ASL RS01.[2] It also remained in prototype condition, which meant the car did not get into production.[5] In early 2022, Tomita announced he was working on setting a limited production run of ZZIIs, but no further information has been disclosed. To promote the car and the revived brand, the ZZII will be placed in a showroom in Kyoto.[6]
In popular media
The ZZII was a regular addition to the Gran Turismo video game series since Gran Turismo 2. It last appeared in Gran Turismo 6.
In Gran Turismo 2, the car's design is completely distinct from the final prototype version since the car was featured when it still was in its first concept iteration, with RWD and 600 PS (440 kW; 590 hp). This car has a more serious look and has an appearance that is similar to that of a GT1 race car, as it was intended to be a true road going racecar.[7] Soon afterwards, the concept was turned into a GT-style car with AWD and a more gentle power delivery. The car featured in Gran Turismo 3 and later games is based on this concept design.
The definitive design of the car was only featured in the GT Pro Series. The Gran Turismo games from Gran Turismo 5 and Gran Turismo 6 never saw their polygonal models updated since it was first added in Gran Turismo 3: A-Spec and after the car was finished.[citation needed]
