Dante Giacosa (3 January 1905 - 31 March 1996) was an Italian automobile designer and engineer responsible for a range of Italian automobile designs — and for refining the front-wheel drive layout to an industry-standard configuration. ==Front wheel drive breakthrough== When Fiat began marketing the Fiat 128 in 1969 — with its engine and gearbox situated in an in-line, transverse front-drive layout, combined unequal drive shafts, MacPherson strut suspension and an electrically controlled radiator fan — it became the layout adopted by virtually every other manufacturer in the world for front-wheel drive. The approach of unequal drive shafts was crafted by Dante Giacosa. Tranverse engine and gearbox front-wheel drive had been introduced to small inexpensive cars with the German DKW F1 in 1931, and made more widely popular with the British Mini. As engineered by Alec Issigonis in the Mini cars, the compact arrangement located the transmission and engine sharing a single oil sump — despite disparate lubricating requirements — and had the engine's radiator mounted to the side of the engine, away from the flow of fresh air and drawing heated rather than cool air over the engine. The layout often required the engine be removed to service the clutch.〔(【引用サイトリンク】 publisher = Fiat500USA.com )〕 As engineered by Dante Giacosa, the 128 featured a transverse-mounted engine with unequal length drive shafts and an innovative clutch release mechanism — an arrangement which Fiat had strategically tested on a previous production model, the Primula, from its less market-critical subsidiary, Autobianchi. Ready for production in 1964, the Primula featured the four-cylinder water-cooled from the Fiat 1100D mounted transversely with the four-speed gearbox located inline with the crankshaft. With a gear train to the offset differential and final drive and unequal length drive shafts. The layout enabled the engine and gearbox to be located side by side without sharing lubricating fluid while orienting the cooling fan toward fresh air flow. By using the Primula as a test-bed, Fiat was able to sufficiently resolve the layout's disadvantages, including uneven side-to-side power transmission, uneven tire wear and potential torque steer, the tendency for the power of the engine alone to steer the car under heavy acceleration. Fiat quickly demonstrated the layout's flexibility, re-configuring the 128 drive-train as a mid-engined layout for the Fiat X1/9, and the compact, efficient layout — a transversely-mounted engine with transmission mounted beside the engine driving the front wheels through an offset final-drive and unequal-length driveshafts — subsequently became common with competitors〔(【引用サイトリンク】 publisher = Automobile Magazine, August 2012 )〕 and arguably an industry standard.〔(【引用サイトリンク】 publisher = Classic and Performance Car )〕 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「Dante Giacosa」の詳細全文を読む スポンサード リンク
