The
Mitsubishi Colt Galant GTO (Gran Turismo Omologato) debuted in 1970 as the flagship
hardtop variant of
Mitsubishi Heavy Industries's then-new Colt
Galant sedan.
The Colt Galant GTO exterior was penned by Hiroaki Kamisago, who had previously been sent by
Mitsubishi to study at the

Firebird and
Cougar, including a long
hood, raised cut-off ducktail rear, and rounded quad-headlamps and tail-lamps. It was also the first Japanese passenger car to have full, roll down, side windows and a
pillarless design.

Rallying, including the famous Japanese Alpine Rally.
Initially, there were three Colt Galant GTO models offered, all powered by the

M1 (1600

M2 (1,600 cc SOHC, 5-speed) and the top-spec
MR (1,600 cc
twin-carb,
DOHC 5-speed), a version only available in Japan.
In 1972 Mitsubishi upgraded the power plants with their new
Astron units. The range now consisted of the
LS (2,000 cc single-carb,
automatic transmission),
GS (2,000 cc twin-carb, 5-speed
manual) and
