Repair-It

The GT included a 125 hp 2.8-liter V6,[1] which grew to a 3.1L in 1991, and the Z51 suspension package with 15-inch styled steel wheels and Goodyear Eagle GT tires. Also included was a sport cloth interior and sport steering wheel. The GTU was available from 1988–1990. Beretta GTUs (with the FE7 suspension package) were shipped to Cars and Concepts where they were equipped with 16x7-inch aluminum alloy wheels, custom ground effects, a rear spoiler, mirrors, custom trim, and decals. With the FE7 suspension the GTU was capable of 0.92 G on the skidpad, well above most cars in its class. GTUs were only available in black, red and white.

The GTZ, which replaced the GTU, was the high-performance version of the Beretta. It was produced from 1990 to 1993. It came standard with Oldsmobile's 2.3 L high output Quad 4 I4, which produced 180 hp (134 kW) and 160 lb·ft (217 N·m) of torque. Also standard was a Getrag five-speed manual transmission and GM's FE7 performance suspension.

The car posted a 0-to-60 mph time of 7.6 seconds and one of the fastest slalom speeds of any front wheel drive car tested. Motor Trend's only complaint was the Quad 4's NVH (noise, vibration and harshness) and noted it was one of the most raucous engines of its time. Beginning in 1991, the 3.1 L V6 could be had as an option on the GTZ, but it was only available with a three-speed automatic transmission that increased the 0-to-60 mph time to around 9.0 seconds

RX-7 GTUs (1989-1990)

In 1989, with the introduction of a face-lifted FC RX-7, and to commemorate the RX-7's IMSA domination, Mazda introduced a limited model labeled the GTUs. Starting with the lightweight base model GTU, which came with manual windows, no rear wiper, the sunroof and A/C was dealer optioned, the GTUs added items found on the Turbo model such as four piston front brakes, rear ventilated brake rotors, vehicle speed sensing power steering, 1 piece front chin spoiler, cloth covered Turbo model seats, leather wrapped steering wheel, 16 inch wheels, 205/55VR tires, and a GTUs-only 4.300 Viscous-type limited slip differential (all other FC LSD's where 4.100). This allowed quicker acceleration from the non-turbo powered 13B. Mazda built 1100 GTUs's in 1989, with the last 100 re-stamped as 1990 models.
