The engine employs an L-Jetronic fuel injection system and a camshaft angle sensor instead of a distributor. The seats were also upgraded, incorporating more support in the side bolsters, and taller headrests. Standard transmission was 5-speed manual. Although many parts of the interior and body were different, the most notable changes were the headlights: the first generation's retractable headlights had been exchanged for fixed ones. By the early 1980s, roadsters had all but vanished from the market, sacrificed to the increasing safety and anti-pollution regulations everywhere. For Europe, two engines are offered: the same 2. Technologies like traction control and stability control were added to increase driveability.
Car and Driver magazine and numerous owners confirmed the missing power, and Mazda was forced to offer to buy back the 2001 cars due to those misleading power claims. The upgraded engine was rated at 157 kW 201 hp. The exterior styling harkens back to the original design while adopting a clean, more muscular profile. The chassis was substantially braced to meet new side-impact standards, most obviously by adding a bar between the seatbelt towers inside the car, but also to the front and rear subframes. Traction control is an option available on some models.
The new car had grown slightly in width compared to the earlier model with dimensions: length 3955 mm 155. Fuel economy city 25 mpg Exterior length 155. The new generation was slightly more aerodynamic than the original, with a Cd figure of 0. After some minor changes in the design, the project received final approval on January 18, 1986 and the car was now codenamed P729. Overall dimensions were 3970 mm 156. This lower-powered model did not receive all the additional chassis bracing of the new 1. Suspension was an independent double wishbone on all four wheels, with an anti-roll bar at the front.
Still in the 2004 model year, a division of Mazda in Japan produced a limited run of 350 Roadster Coupés with an integral hardtop roof, effectively making this a coupé instead of a roadster. The intake runners in the head were straightened and the intake manifold was mounted higher up. Power output of the new engine was quoted at 105 kW 140 hp with 119 ft·lbf 161 N·m of torque.

In Japan, the car was not badged as a Mazda, as the company was experimenting with the creation of different marques for deluxe models, similar to Nissan's Infiniti and Toyota's Lexus. The engine compression ratio was raised from 9. Some cockpit elements were also changed, with instrument panel gauges having a white face and red numbers. In the United States, Mazda erroneously quoted the power figure for the Japanese and Australian model in early catalogues. The body was strengthened, gaining 16% in bending rigidity and 22% in torsional rigidity. The upgraded tires and suspension allowed the new model to pull 0. In some markets such as Europe, the 1.
The intake cam was changed to a solid lifter design with a stronger cam. Adding 37 kg 82 lb to the weight of a comparable model with soft top, the hard top takes 12 seconds to raise or lower; in a departure from the competition, it does not take any of the existing trunk space when folded down. The Duo 101 design, so named as either a soft-top or hard-top could be used, incorporated many key stylistic cues inspired by the Lotus Elan, a 1960s roadster widely considered as one of the best-handling sports cars of its day. The new engine produced 98 kW 130 hp , increased to 133 hp 99 kW from 1995. The project was moved to Japan for final engineering details and production issues to be decided. No exterior changes were made, though. Despite the success in maintaining enough external similarities, the third generation shares no components with the second generation, except for the side-panel turning-lights on the European-spec models.
Engine bore x stroke 3. An optional hardtop was made available at the same time, in reinforced engineering plastic. No Roadster Coupes were exported outside Japan. The intake and exhaust system also received a minor upgrade. It comes with a longitudinally mounted four cylinder engine coupled to a manual transmission an automatic transmission is available as an option. Owners who did not take up the buy back offer were offered an apology and free servicing for the warranty period.
Inducing oversteer is easy and very controllable. The body structure was reworked to incorporate the roof for a substantial increase in chassis rigidity and a weight increase of 10 kg 22 lb. . Mazda's Variable Intake Control System system was introduced, which effectively gave a long narrow intake mainfold at low rpm for better swirl, changing to a short, free-flowing manifold at high rpm for maximum breathing. The price premium is expected to be less than the cost of a separate hard top. With the minimum of options, the 2001 model weighed 1065 kg 2350 lb. Performance was improved slightly, the additional power being partly offset by the extra weight.
