Toyota Celica

Up until 1976, U.S. Celicas got either wheel covers (ST, LT) or styled steel wheels with trim rings (GT) in the 13-inch size. Starting in 1976, all Celicas got 14-inch styled steel wheels, with trim rings (GT) or without them (ST and LT).
The TA22 Celica also had removable vents mounted in the hood which the RA23 and RA28 lacked, while the TA27 and RA25 models had three raised fluted vents inset into the bonnet. The RA series also had an elongated nose to accommodate the larger engine. The bonnet/hood vents, fuel filler cap and interior options were also different between the TA and RA series across the model range.
For 1976–1977, the non-US GT Liftback was also available with the 18R-G twincam engine with a Yamaha head and running gear. This engine produced significantly more power than the single-cam 18R. Peak power was about 100 kW (134 hp) at 6000 rpm.
