A class written for two hundred cars

Two hundred examples in twelve consecutive months, with no restriction on drive layout or induction. Read the class

Lead photograph · Loose-surface speed is what the four-wheel-drive concession bought; spectator distance is what the rules were later rewritten to fix.

Three cars, one permissive sentence

Section 02 · Group B

2.2

Audi Quattro

Ingolstadt built a four-wheel-drive rally car once the regulations stopped forbidding one.

The entry

A boxy mid-engined Group B rally car in white competition livery with its rear clamshell raised, showing an engine carrying both a supercharger and a turbocharger, workshop floor

2.3

Lancia Delta S4

Abarth in Turin read a rulebook that limited neither supercharging nor turbocharging and fitted both.

The entry

A mid-engined four-wheel-drive rally car of the mid-1980s in competition livery, boxed wheel arches and a large rear wing, rear bodywork tilted up to expose the transverse engine behind the seats, service park

2.4

Peugeot 205 T16

Mid-engined and four-wheel drive, sharing a name with a front-wheel-drive hatchback and very little else.

The entry

Every one of these cars exists because of a sentence in a document.

The signature of every entry: name the clause, then the car it produced
