The Lotus 907 is an inline-4 automobile engine designed and manufactured by Lotus Cars. Displacing 1,973 cubic centimetres (120.4 cu in), it is all-alloy, and features dual overhead camshafts (DOHC) and 16 valves. It developed approximately 144 bhp (107 kW) with dual side-draft Dell'Orto carburetors in most markets and Zenith Stromberg carburetors for US cars. It was nicknamed "The Torqueless Wonder" for its lack of bottom end but good high end horsepower.[citation needed]
The Lotus 907 was the first production variant of the Lotus 900 series engine. The Jensen-Healey was the first production car to receive the 907.
It is said that when Vauxhall unveiled its new slant-four engine at the 1967 Earls Court Motor Show its bore centres were exactly the same as those proposed by Lotus.[1]: 38 Colin Chapman immediately negotiated a deal with Vauxhall to buy some of their cast-iron blocks so that development of Lotus' own aluminium cylinder head could be sped up to produce the 907 engine.
