The Benetton B186 was the Formula One car built and raced by the Benetton team for the 1986 Formula One season. It was the first car to be constructed and raced by Benetton, which had bought the Toleman team at the end of after several years of sponsoring it and other teams, including Alfa Romeo and Tyrrell. The B186 was a competitive car: in the hands of drivers Gerhard Berger and Teo Fabi, it set two pole positions, three fastest laps, and was victorious at the 1986 Mexican Grand Prix. The Benetton B186, along with the Brabham BT55, Arrows A9 and other BMW engined- cars in 1986 are the most powerful Grand Prix cars ever built. The B186 in particular, being the most competitive of the BMW engined cars that season could throw out 1,350+ hp in qualifying trim, and about 900 hp in race trim. ==Concept== Despite the buyout of the small Toleman team by the financial power of the Benetton Group, its organisation and structure remained largely unchanged. Peter Collins stayed on as team manager, whilst Rory Byrne continued as chief engineer. The planned 1986 chassis, labelled the Toleman TG186, was simply renamed as the Benetton B186. The team also remained based at its Witney headquarters in England.〔Ménard (ed.), pp.144-145〕 However, Benetton had the resources to pay for a supply of engines produced by a large car manufacturer, BMW, which replaced the privateer Hart units which had powered Toleman's F1 chassis since the team's début in the series in .〔Hamilton (ed.), p.49〕 The focus of BMW for 1986 was the new "lay-down" version of its M12/13 engine, designed for the revolutionary Brabham BT55 chassis, whilst the standard "upright" version was supplied to Benetton and the Arrows team.〔Spurring, p.162〕 Both the BMW M12/13 and Hart engines used the 4 in-line configuration, meaning that not too many adjustments needed to be made to the general design concept of the B186 in comparison to the previous year's Toleman TG185. However, the chassis was refined and tidied up in several areas, such as the sidepods, to produce more aerodynamic downforce. The B186 was also designed to be structurally stronger than its predecessor, as the turbocharged BMW engine was about more powerful than the turbocharged Hart 415T engine in race trim (and about more in qualifying) and thus put more stress on the chassis.〔 Indeed, in terms of maximum horsepower, the BMW engines provided to Benetton, Brabham and Arrows were the most powerful in the series.〔 One of the main challenges faced by Byrne and the Benetton design team was to produce a comfortable cockpit for the team's two vastly different drivers: the short (approximately ) Teo Fabi and the tall Gerhard Berger.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Benetton B186」の詳細全文を読む スポンサード リンク
