The first-generation Volvo S80 (P2 platform) marked a historic turning point for the Swedish manufacturer. Replacing the S90 (rear-wheel drive), it introduced the transverse engine and front-wheel drive (or AWD all-wheel drive) architecture for the brand's top-of-the-range models. Designed by Peter Horbury, it introduced the famous broad shoulders that would become Volvo's stylistic signature. It was also a technological laboratory: it was one of the first cars in the world to use an intensive multiplexed network (CAN-bus), which led to serious early electronic problems (1998-2001). The mid-life facelift (2003, model year 2004) corrected almost all of these defects, refined the aesthetics (grille, lights, chrome-ringed gauges) and introduced excellent engines (2.5T, evolution of the D5).

The Volvo S80 I is a fantastic executive car that suffered from its status as a technological pioneer. Models produced between 1998 and 2001 are to be avoided due to chronic electronic problems (fickle multiplexing, faulty ETM throttle body). However, from the 2003 facelift (MY2004) onwards, reliability becomes excellent. The best choice is the 2.5T petrol engine or the D5 (163 hp) diesel, provided the automatic gearbox has been regularly serviced. Absolutely avoid the T6 version, whose GM gearbox is a ticking time bomb. A well-maintained post-2003 S80 is an extremely relevant 'youngtimer' or high-mileage purchase.
