    racing these in a league with simracingaustralia on sundays and its awesome with the league cars parity.

    With selection of different engines is there anyway to have that in setup rather than having to go out and reselect cars?

    Some of the sound files for the ferrari (the one i'm driving in series) is a bit disjointed when boost sound cuts in.
    Also the manufacturer of the lotus rims is FONDMETAL.

    Concept
    The Zakspeed 861 was a single seat open wheel racing car, designed and built by the German Zakspeed team for the 1986 Formula One world championship. It was a development of the Zakspeed 841 used during the 1985 Formula One season. Changes were largely to reduce weight and complexity over its predecessor. In its second year in Formula One, the tiny Zakspeed team continued to be only competitor, other than the large factory teams of Ferrari and Renault, to design and build its own engines.

    Chassis and suspension
    The chassis was built around a carbon fibre/kevlar composite monocoque. The reduction in fuel tank size to 195 litres for the 1986 season allowed the car to be smaller, allowing better airflow to the rear wing. Despite the efforts to reduce weight, the car, although close to the 575 kg minimum weight limit for the formula, was still too heavy.[3] The car again appeared in the red-and-white corporate colours of West cigarettes, who remained as title sponsor.

    The suspension was double wishbone all round, operating springs and dampers by pullrods.[3]The car started the season with conventional steel brakes, but Zakspeed experimented with carbon-carbon brakes from Monaco and raced them from Germany. The team continued its tyre supply contract from American firm Goodyear.

    Despite the improvements over the 841, by the end of the year the chassis, whose concept dated back to 1983, was considered outdated. Technical director Helmut Barth commented that "It was too big and had too much drag".[4]

    Engine and transmission
    The Zakspeed designed 1.5 litre turbocharged engine shared its inline-4 layout with the Hart and BMW engines, of which by 1986 only the BMW (with the Benetton team) was still competitive (the Hart engine wasn't seen in F1 after the 1986 San Marino Grand Prix). Like both those engines, the Zakspeed was mounted semi-stressed in a spaceframe cradle. The year was dominated by the bespoke V6 engines of Honda and TAG-Porsche. During the 1985 season, the team had worked on developing their own electronic fuel injection system, while using a mechanical injection system in races. For the 1986 season, the team reached an agreement to use a low pressure Bosch Motronic electronic fuel injection system, originally intended for Alfa Romeo's stillborn inline four turbo. This improved throttle response, drivability and fuel consumption. In race trim the engine was reported to exploit pressure of around 3.6 bar, roughly 3.6 times atmospheric pressure, which corresponded to about 850 bhp (634 kW; 862 PS). In qualifying boost could be raised as high as 4.5 bar, with correspondingly greater power (approximately 1,000 bhp (746 kW; 1,014 PS)).[4] These figures are comparable to that year's championship winning McLaren MP4/2-TAG/Porsche, which officially produced 850 bhp at 3.3 bar in race trim, although the TAG unit was far from the most powerful in Formula One that season (that title belonged to the special BMW qualifying engines which produced a reported 1,400 bhp (1,044 kW; 1,419 PS)).

    Another masterpiece by Chief!! :D Hoping for a soon release with happiness!
    Indeed, it's the A8 Arrows. According to Wikipedia, was used at 1985 for the entire season, and in 1986 was used at every race, except Germany and Austria where Thierry Boutsen used the A9 (Christian Danner used the A8, scoring points in Austria with a 6th place), and Danner used the A9 just in Hungary (and Boutsen used the A8 at that race). The rest of 1986, both drivers used the A8, same as 1985.

    a slight off topic:
    I was thinking "it would be so cool to see these cars drive the Jacarepagua circuit in Rio once again, that track was so cool". Then I thought "I wonder what the Jacarepagua track looks like now"...
