Mazda RX-8: Wankel engine, generations and buying advice
The Mazda RX-8 (2003–2012) is a four-seater sports coupe with a rotary Wankel engine and rear-hinged doors. We look at the generations, engines, and key points to check before buying.
RX-8 in brief
The RX-8 is the only production four-seater coupe with a Wankel rotary engine. The rear doors are smaller and open in the opposite direction, making it easy to get into the back seats, although they aren't spacious.
The car is renowned for its excellent balance, precise handling, and high revs, but the rotary engine requires specific maintenance and evaluation.
Which version to choose
In Europe, there were two engine power versions: around 192 HP (with a 5-speed gearbox) and around 231 HP (with a 6-speed gearbox). The more powerful version is often pricier but also sportier.
Around 2008, the RX-8 was refreshed: it got a facelift and some updated features. Later versions are usually better equipped, but the key thing is the engine's condition.
Engines and gearboxes
All versions have a 1.3-litre twin-rotor Wankel engine (Renesis). It's known for high revs and relatively high fuel and oil consumption.
Gearboxes are manual (5 or 6-speed) or automatic. Most buyers opt for the manual.
What to check when buying a used RX-8
The engine's condition is crucial: ask for a compression test, as worn rotor seals are expensive to repair. Check if the engine starts easily, especially when it's warm.
Check the oil level (the rotary engine uses oil partly due to its design), spark plugs and belts, cooling system and timing chain. Many cars were driven short distances, which is detrimental to the engine.
Trims
Names and equipment vary by market and year; we list the trims most commonly found in Europe.
192 AG
2003–2012Less powerful version with a 5-speed gearbox.
- Around 192 hp
- 5-speed gearbox
- Often — simpler equipment
231 AG

- Around 231 hp
- 6-speed gearbox
- Often — sportier equipment
Ankstyvieji (iki ~2008 m.)
2003–2008The first production run before the facelift.
- Original styling
- Often comes with more basic equipment
- Higher risk of age and wear-related issues

Comparing versions
| 192 AG | 231 AG | Atnaujintas | |
|---|---|---|---|
| Who it suits | For daily spirited driving | For driving comfort | For a more modern take |
| Power | Around 192 hp | Around 231 hp | Depends on the version |
| Gearbox | 5-speed | 6-speed | 5 or 6-speed |
| Price in the used market (relatively) | Mid-range | High-end | High-end |
For most buyers, it's best to choose a car with a well-maintained engine rather than just focusing on power. The 231 hp version is sportier, but a good service history is even more important.
