Both the Lumina and Z34 have a single catalytic converter but the Z34's exhaust utilizes two mufflers to release its gases. Small changes in the exhaust system reduce back flow pressure in the Z34. The four-speed automatic was also stepped up the Hydra-Matic 4T60-E from the ME9 but is half a second slower 0-60 and loses 10 hp (7 kW). The Z34 was geared for fast driving producing a 7.5 second 0-60 mph time and a 15.8 in the quarter mile. The standard MG2 used in Luminas was upgraded to the Getrag 284 five-speed transmission with a final drive ratio of 3.67:1. In order to accommodate the extra horsepower, transmission improvements were needed. Upwards of 7,200 rpm the fuel delivery is cut off and the valves float to avoid engine damage.

m) of torque at 4,400 rpm, and a compression ratio of 9.25:1 (9.50:1 when equipped with a manual transmission).

This simplistic and reliable design puts out 210 hp (157 kW) at 5,200 rpm, an impressive 215 ft For example, the Z34 has oil reserves in the valve train to reduce wear at start up, an oil to water cooler, and a windage trey to avoid foaming. Improvements have also been made in the cooling system, ignition, and oiling system to accommodate more moving parts. Cylinder walls were thickened and bearings were reinforced and polished to handle the increased load. The connecting rods and crankshaft are shared although the metallurgy has been altered to handle the additional horsepower of the 3.4L engine. To keep manufacturing new parts to a minimum, the TDC shares the same bore (84 mm) as the 3.1-3.4's but contrary to popular belief it does not share the same stroke with the Chevy 2.8l, the 2.8 has a 2.99' stroke whereas the other 60 degree v6's (3.1's & 3.4's) have a stroke of 3.31'. Aluminum heads in a pent-roof design and valve clearance notches in the pistons also uphold the high-revver's capacity. The TDC engine incorporates racing engine technology with its valve configuration to attain a 7000 rpm redline. They did this to get the performance of Japanese four cam engines while keeping prices reasonable. GM's engineers used the same block as the 2.8-3.1 60 degree V-6 for this four cam achievement.

The Twin Dual Cam V-6 is the most respectable upgrade in the Z34. These are all driven by a Bose amplifier, which is tucked away in the trunk lid. All factory Delco speakers were replaced by Bose with door speakers being installed rather than dash speakers. The Z34 also offered an optional Bose stereo system. The cloth fabric is Scotchgard protected to avoid annoying stains.

The Z34's driver seat has three adjustments, one to slide back and forth, one for back adjustment, and the third tilts the entire seat. On the favorable side, one of the best aspects of the Lumina's interior is its leg and headroom for the driver and passenger. Some critics are also disappointed with the heavy doors, the high mounted third brake light, and the difficulty in getting in the back seat. Both have common complaints: a tiny glove box, small instruments, overly plump seats, no cup holder, and climate control buttons that require a stretch to use. The interior of the Z34 has subtle changes compared to the Lumina. The Z34 nameplate is labeled proudly along the stripe in the manner of the Z28, Z26 and Z24.

The rear of the Z34 also differed from other Luminas by the License plate being relocated from the bumper to in between the taillights. The rear end of the car is enhanced with a wing and a bumper accenting the dual exhaust outlets. Louvered slots in the hood pull some heat out of the engine compartment. Ground skirts that run along the side of the car give the appearance of a lower ride. The front fascia includes a low profile airfoil before the radiator and a closed grill with slotted turn signal openings. The Z34 spices up the exterior of the Lumina with a collage of ground effects although paint colors are limited to white, red, black, gray, and light blue. Vast improvements in aerodynamics and body design helped support confidence when the Lumina was driven to victory a majority of the Winston Cup Circuit. This mid-sized sedan was manufactured to follow in the Monte Carlo's footsteps of gaining the most NASCAR victories in history. In 1989 Chevrolet replaced the popular Celebrity and Monte Carlo with the Lumina, a front-wheel drive car using the GM-10 or W-Body platform.
