159 amazing chassis
1)156 used to be small by class standard, so predictably, 159 has grown considerably larger. It is 4,660 mm long (+230mm), 1,828 mm wide (+78mm) and with a wheelbase of 2,700 mm (+100mm). However, Giugiaro emphasis a sporty profile, thus actually reduces its height by 3 mm to 1417 mm
2)Inside, although we have no pictures to prove, Alfa promises a driver-focused design, with wrap-around center console and all instruments turned towards the driver.
3)This platform employs sophisticated double-wishbones front and multi-link rear suspensions. It is either FWD or 4WD, the latter by Alfa's Q4 system. The Q4 employs a Torsen C center differential to transmit 57% torque to the rear axle normally and provides limited slip function when one axle spins. It is therefore more rear-biased than Audi's Quattro system
4)One of the most remarkable things is chassis rigidity – the chassis of 159 achieves 31400 Nm / degree, a figure so high that I'm afraid only VW Phaeton can exceed. For instance, Opel Vectra and Saab 9-3 are 18,000 and 20,000 Nm / degree respectively. The 159 uses multi-ply sheet metal, extensive laser welding, boxed element structure etc. to achieve high rigidity. This benefits crash protection, NVH suppression as well as handling
