The BMW 320si is a rare homologation special variant of the E90 saloon, and is something of a 'hidden gem' among non-M cars of this generation. With its rev-happy race-derived engine and engaging manual transmission, this is a practical and refined executive saloon that is also a fun driver's car, this car benefits from a new mot and top engine rebuild alongside a new timing chain fitted and recent oil service, the ac has been re-gased recently. KEY FACTSA rare BMW homologation special, created for the World Touring Car Championship entry, presented in good condition and with relatively low mileage.Under the bonnet is a hand-built 2.0-litre N45 inline-four developed for the E90 FIA WTC, producing up to 173hp at 7,000rpm, and driving the rear wheels through a six-speed manual transmission.The car benefits from a top engine rebuild and timing chain and a new exhaust. .EQUIPMENT AND FEATURES a mere 2,600 examples of the E90 320si were built, with only 500 made for the uk with only about 130 remaining. to homologate the World Touring Car which used the same engine. The inline-four N45 motor was hand-built in the UK, at the same facility that put together the BMW-Sauber Formula One powertrains, with the cylinder head cast alongside the F1 engines.Its visual highlight is the carbon-fibre cam cover. While it saves around 10kg and lowers the centre of gravity, it is also a fantastic aesthetic enhancement to the engine bay.The 2.0-litre engine has an increased compression ratio of 11.0:1, and the cylinder liners are aluminium alloy rather than cast iron. The Valvetronic induction system was omitted. Just like the World Touring Car, it rides on 18-inch Style 216 alloy wheels.The 320si is also equipped with M Sport suspension, the M Sport aerodynamic body kit, and an M leather steering wheel. The car also features BMW Professional audio, rear parking sensors and the through-loading system.Accompanying the car are all original manuals, including the service book.CONDITIONThere is some age related marks to the body work, The alloy wheels have some cosmetic damage, so would benefit from refurbishment.
