The Zytek ZA1348, also known as the Zytek ZA348, is a 3.4-liter, naturally-aspirated, V8 racing engine, designed, developed and produced by British manufacturer Zytek, between 2003 and 2004. It was specifically constructed and built as the spec-engine for the new A1GP open-wheel formula racing series, and debuted in 2005. It powered the Lola B05/52 A1 Grand Prix car. It produced between 520–550 hp (390–410 kW), and around 330 lb⋅ft (450 N⋅m) of torque. A slightly detuned version of the engine, producing around 400 hp (300 kW), but a similar torque figure of 326 lb⋅ft (442 N⋅m), was used in the Ginetta G50Z sports racing car. The engine itself is very light, weighing only 120 kg (260 lb), constructed out of cast aluminum alloy. [3] [4] [5]
