The Ultimate Daily-Usable Supercar Slayer

If you’re a performance junkie looking for the ultimate white-knuckle ride but still need to crush the daily commute or school run in comfort and style, this retina-searing 2018 Ara Blue Audi RS3 Sportback will not fail to impress.

As one of the last non-OPF DAZA-engined RS3s, it already ranks among the most sought-after modern hot hatches. But this example takes things to another level entirely. Not only does it boast £10,850 of desirable factory options, it also features over £14,000 worth of professional upgrades by MRC Tuning, transforming it into a truly ballistic machine.

As one of the UK’s leading Audi RS specialists, as well being expert moderators on the Audi RS Owners Club forum, the Audi RS3 8Y page and Audi RS6GT owners club page, Automotive Addiction has unrivalled experience with all generations of the RS3 platform, having sold over 700 examples to date, and can confirm that this model is up there with the best we have seen.

Stage 3 MRC Tuning – 646PS of Switchable Power

At the heart of this RS3 lies Audi’s award-winning 2.5-litre DAZA 5-cylinder engine, enhanced to full Stage 3 specification by leading VAG performance specialists MRC Tuning. This includes calibration of both the ECU (engine) and TCU (gearbox) software to produce a mind-blowing package.

Thanks to a TTE-700 turbocharger and extensive supporting hardware, this car delivers switchable maps at the touch of a button, allowing you to instantly alter power delivery:

• 646PS on 99RON super-unleaded with octane booster
• 574PS (high-torque map) on 99RON
• 523PS (low-torque map) on 99RON

No matter which mode you select, torque is capped at a safe 700NM, a proven and reliable figure for the DAZA powerplant. The result? A car that can demolish the 0–60mph sprint in under three seconds while still retaining everyday usability.

Supporting Hardware & Upgrades

This RS3 hasn’t just been mapped—it has been meticulously upgraded with proven, high-quality components to ensure maximum performance and reliability:

• TTE-700 Turbocharger (£4,900)
• Forge uprated intercooler (£1,250)
• Eventuri carbon-fibre intake system (£1,800) with turbo inlet elbow (£650)
• BCS hi-flow downpipe with catalyst delete (£1,100)
• Audi RS Sport Exhaust system (for that legendary DAZA 5-cylinder roar)
• Bosch 980cc uprated injectors (£650)
• Reyland 2-piece floating front discs with Ferodo Racing pads (£1,250)

The combination of hardware and mapping not only releases breathtaking power but also produces a steroidal soundtrack—one that’s even more intoxicating thanks to the absence of an OPF filter.

Provenance, Condition & Service History

This RS3 was originally sourced through the Audi RS Owners Club, where it began life as a bone-stock example before its previous enthusiast owner invested heavily into its current specification. Every upgrade and service is backed by receipts and health checks, ensuring peace of mind for the next custodian.

With just 27,600 Audi-diagnostic verified miles and a full record of utterly meticulous care, including a comprehensive Audi Specialist Service History (which records all major service items completed before Audi’s recommended schedule) this RS3 is as solid mechanically as it is visually stunning.

Also, as the previous owners of this weapons grade RS3 are well known customers of Automotive Addiction, we are able to accurately describe and verify the history of this RS3 in complete confidence to any prospective buyers, ensuring unparalleled peace of mind for your new purchase.

• Matrix LED Headlights (£895)
• Panoramic Glass Sunroof (£1,075)
