Review: Alfa Romeo Mk.I 156 sedan (1999-02)
Overview
Released in February 1999, the Alfa Romeo Mk.I 156 was available as a compact executive sedan or wagon (please note that the 156 Sportwagon has been reviewed separately). Manufactured in Pomigliano d’Arco, Italy, the front-wheel drive 156 range initially consisted of 2.0 Twin Spark and 2.5 V6 variants, powered by 2.0- and 2.5-litre petrol engines, respectively. In 2002, 2.5 V6 Monza editions were released with six-speed manual transmissions.
Twin Spark and JTS engines
Of the engines,
- The 2.0-litre inline four-cylinder ‘Twin Spark’ engines had double overhead camshafts, four valves per cylinder and a compression ratio of 10.0:1. The Twin Spark engines were so-called because one spark plug was positioned in the centre of the cylinder, with a second spark plug positioned at the very edge of the combustion chamber between the inlet and exhaust valves; and,
- The 2.5-litre V6 had double overhead camshafts, four valves per cylinder and a compression ratio of 10.3:1.
While the 2.0 Twin Spark was available with five-speed manual and semi-automatic transmissions (Alfa Romeo’s ‘Selespeed’), the 2.5 V6 was offered with a four-speed automatic transmission.
Dimensions and suspension
The 156 sedan was 4430 mm long, 1745 mm wide, 1415 mm tall and had a 2595 mm long wheelbase. Furthermore, the 156 had double wishbone front suspension and MacPherson strut rear suspension.
