1974
VOLVO 264
At Volvo the PRV V6 wore its own codes — B27, B28, B280. The very first PRV ever fitted in a car went into a Volvo 264 in October 1974, and Volvo saloons kept the V6 alive until 1997, five years after the divorce from Renault.
Volvo joined Peugeot and Renault in 1971, taking an equal share of the alliance — and got the honour of the first engine: the first PRV officially fitted under a bonnet went into a Volvo 264 in October 1974. Where Douvrin engines carry Z-codes, Volvo used its own B-codes: B27, B28, then B280.
Despite the divorce from Renault in 1992, the PRV soldiered on in Volvo saloons until 1997 — the full story is in History.
A stately footnote: stretched 70 cm and bodied by Bertone, the Volvo 264 TE carried the PRV as the official limousine of East German leadership — Erich Honecker rode in its back seat. The story is in Pop culture.
The Renault/Peugeot/Citroën Z-codes — and every known engine code.
