North American models received a different instrument cluster (the NA S3 RX-7 is the only rotary-engined car to not have a centrally mounted tachometer). GSL package was continued into this series, but Mazda introduced the GSL-SE sub-model. The GSL-SE had a fuel-injected 1.3 L 13B RE-EGI engine producing 135 hp (101 kW) and 135 lb·ft (183 N·m). GSL-SEs had much the same options as the GSL (clutch-type rear LSD and rear disc brakes), but the brake rotors were larger, allowing Mazda to use the more common lug nuts (versus bolts), and a new bolt pattern of 4x114.3 (4x4.5"). Also, they had upgraded suspension with stiffer springs and shocks. The external oil cooler was reintroduced, after being dropped in the 1983 model-year for the controversial "beehive" water-oil heat exchanger. The 1984 RX-7 GSL has an estimated 29 highway miles per gallon (8.11 litres per 100 km) /19 estimated city miles per gallon (12.37 l/100 km). According to Mazda, its rotary engine, licensed by NSU-Wankel allowed the RX-7 GSL to accelerate from 0 to 50 (80 km/h) in 6.3 seconds. Kelley Blue Book, in its January--February 1984 issue, noted that a 1981 RX-7 GSL retained 93.4% of its original sticker price. 1985 - Mazda released in Australia the RX7 Finale - this was the last of the series and brought out in limited numbers. The Finale featured power options and a brass plaque mentioning the number the car was as well as "Last of a legend" on the plaque. The finale had special stickers and a blacked out section between the window & rear hatch. The handling and acceleration of the car were noted to be of a high caliber for its day. This generation RX-7 had "live axle" 4-link rear suspension with Watt's linkage, a 50/50 weight ratio, and weighed under 2500 lb (1100 kg). It was the lightest generation of RX-7 ever produced. 12A-powered models accelerated from 0--60 mph in 9.2 s, and turned 0.779g (7.64 m/s²) laterally on a skidpad. The 12A engine produced 100 hp (75 kW) at 6000 rpm, allowing the car to reach speeds of over 120 miles per hour (190 km/h). Because of the smoothness inherent in the Wankel rotary engine, little vibration or harshness was experienced at high rpm, so a buzzer was fitted to the tachometer to warn the driver when the 7000 rpm redline was approaching. The 12A engine has a long thin shaped combustion chamber, having a large surface area in relation to its volume. Therefore, combustion is cool, giving few oxides of nitrogen. However, the combustion is also incomplete, so there are large amounts of partly burned hydrocarbons and carbon monoxide. The Exhaust is hot enough for combustion of these to continue into the Exhaust. An engine driven pump supplies air into the Exhaust to complete the burn of these chemicals. This is done in the "thermal reactor" chamber where the Exhaust manifold would normally be on a conventional engine. Under certain conditions the pump injects air into the thermal reactor and at other times air is pumped through injectors into the Exhaust ports. This fresh air is needed for more efficient and cleaner burning of the air/fuel mixture.[2] Options and models varied from country to country. The gauge layout and interior styling in the Series 3 was only changed for North American versions. Additionally, North America was the only market to have offered the first generation RX-7 with the fuel-injected 13B, model GSL-SE. A turbocharged (but non-intercooled) 12A engine was available for the top-end model of Series 3 in Japan. Sales were strong, with a total of 474,565 first generation cars produced; 377,878 were sold in the United States alone. In 2004, Sports Car International named this car #7 on its list of Top Sports Cars of the 1970s. In 1983, the RX-7 would appear on Car and Driver magazine's Ten Best list for the first time in 20 years I created this video with the YouTube Video Editor (http://www.youtube.com/editor)

Mazda RX-7 Crash at 225 MPH!!
Bonneville Salt Flats: 3rd gen Mazda RX-7 race car trying to beat the land speed record for a production vehicle. At this speed, the tire patch that is touching the ground is LESS than the width of your index finger across each tire. Furthermore each patch is encountering dust and small sand-like particles often. If you could keep the pace with this car and remain standing next to it, you could reach over and push it away from you sideways with little effort. The announcer claims that an additional burst of oxygen in the fuel causes a loss of control, but in all likelyhood, the wind just changes ever so slightly, or began to blow (even lightly) and it was actually this that nudged the cars nose off by just enough to start a flat spin. Yes, a flat spin, like an airplane goes into! No rudder on this vehicle, so no control!
