Mazda RX-7 FD

The Mazda RX-7 FD, also known as the third-generation RX-7, is one of the most iconic Japanese sports cars ever produced. Built between 1992 and 2002, it elevated Mazda's rotary-engine legacy to new heights with its stunning design, cutting-edge technology, and high-performance capabilities. Here's a detailed look at the RX-7 FD:

1. Rotary Engine:

• Engine Type: 13B-REW twin-rotor Wankel rotary engine.
• Displacement: 1.3 liters (just like the FC, this is calculated differently due to the rotary design).
• Power Output:
  • Early versions in Japan produced around 252 horsepower, while the US version started with 255 horsepower.
  • In later years, power increased slightly in Japan, up to 276 horsepower, thanks to Japanese market regulations and continuous improvements.
• Twin-Turbocharger System: The FD's 13B-REW engine featured sequential twin turbos, which meant one turbo spooled at lower RPM for better response and the second turbo came in at higher RPMs to deliver more power. This provided both low-end torque and top-end power, making it one of the most sophisticated engines of its time.
• High Revving: As a rotary engine, the FD’s 13B-REW was known for revving high, with its redline around 8,000 RPM.

2. Design and Styling:

• Aerodynamic Shape: The RX-7 FD has a timeless and incredibly sleek design, with smooth, flowing lines that emphasize its low, wide stance. The pop-up headlights, rounded curves, and aggressive yet elegant front fascia contributed to its exotic look.
• Weight Reduction: The FD was designed with weight savings in mind. Its lightweight construction (around 2,800 lbs) helped it achieve a near-perfect 50:50 weight distribution, crucial for its outstanding handling.
• Interior: The cockpit-style interior was very driver-centric, with the dashboard angled towards the driver. The RX-7 FD also kept the cabin simple, avoiding unnecessary features that would add weight.

3. Handling and Performance:

• The FD RX-7 is revered for its nimble handling. It uses a multi-link rear suspension and double wishbone front suspension, paired with its lightweight design, to provide exceptional balance and cornering ability.
• 0-60 mph in the mid-5 second range and a top speed of around 155 mph.
• Mazda used extensive engineering refinements to keep the FD agile and connected, making it a favorite in both street driving and competitive motorsports.

4. Advanced Technology:

• The FD's sequential twin-turbo system was cutting-edge for its time. It delivered power in stages, smoothing out the lag associated with single, larger turbochargers and providing a more seamless driving experience.
• Other tech features included lightweight materials, such as an aluminum hood, and clever engineering solutions to keep the car both light and rigid.

5. Models and Variants:

• Base Model: Standard features included the twin-turbo 13B engine, sports suspension, and a minimalist, driver-focused interior.
• R1 (US) or Type R (Japan): These models were track-oriented versions with stiffer suspension, front and rear spoilers, and additional oil coolers.
• Type RS and RZ (Japan): Later high-performance versions introduced in Japan with more power, better suspension, and lighter weight.
• Spirit R (2002): The final and most coveted version of the RX-7 FD, the Spirit R, was only available in Japan. It came in three different variants (A, B, C), with the Type A being the most performance-focused (manual transmission, lightweight, track-ready).

6. Cultural Impact:

• The RX-7 FD is a cult classic and a symbol of 90s Japanese performance cars. It has appeared in numerous video games (like Gran Turismo and Forza), movies (notably the Fast & Furious series), and remains highly regarded in car enthusiast communities.
• The FD is a favorite in the tuning and modification world, as its rotary engine can be modified for extreme power gains, although this sometimes comes at the expense of reliability.

7. Motorsports:

• The RX-7 FD was a successful car in racing as well. It competed in various series, including the 24 Hours of Le Mans and GT racing, where it proved its mettle as a high-performance machine.

8. Legacy:

• The FD generation RX-7 is considered one of the greatest sports cars of its time and remains a dream car for many enthusiasts today. Its combination of a unique rotary engine, lightweight chassis, and timeless design make it a true classic.
• While the rotary engine requires more maintenance than conventional engines, its high-revving nature and distinctive character continue to draw admiration.

In conclusion, the Mazda RX-7 FD is a masterpiece of 90s sports car engineering, blending cutting-edge rotary engine technology, advanced aerodynamics, and a focus on lightweight performance. Its legacy as one of the finest handling and best-looking cars ever produced is still strong today.
