B6304S[edit]

The B6304S was the first generation of modular inline-6 engines. It has the same bore and stroke (83x90 mm) as the B6294, but the deciliter number was rounded up (i.e. 2,922 cc to 3,000 cc). These engines produced 204 hp (152 kW; 207 PS) at 6000 rpm, and 197 lb·ft (267 N·m) of torque at 4300 rpm. Engine output was reduced to 180 hp (134 kW; 182 PS) and 199 lb·ft (270 N·m) by changing the cam profile (back then without variable valve timing) in favour of emissions regulations.

To develop this new, modular engine type, Volvo had a cooperation project with Porsche / Weissach.
