The Mercedes-AMG SL 63 is a sporty roadster with plenty of power, but Manhart wants to elevate it to supercar levels of performance. The SL 700 R, which is limited to 10 units, features significantly increased power and torque figures, alongside optional chassis upgrades and mild visual tweaks.
Starting with the engine, the twin-turbo 4.0-liter V8 went from the stock 577 hp (430 kW / 585 PS) and 800 Nm (590 lb-ft) of torque to a healthier 697 hp (520 kW / 707 PS) and 935 Nm (690 lb-ft). Those numbers are impressive, to say the least, but slightly detuned compared to the initial expectations for the SL 800 R that was previewed last year.
The power bump was achieved thanks to the MHtronik powerbox, a revised intercooler setup, and a new air filter. Additionally, sport downpipes with 600-cell catalytic converters are available as an option for export markets outside Germany. Power is transmitted to all four wheels through the 4Matic+ system and the 9-speed automatic gearbox which has been upgraded accordingly.

Unlike other tuning projects, Manhart didn’t change anything on the bodywork and the stock aerodynamics package of the Mercedes-AMG SL, besides adding the signature gold decals and a matching paint for the re-branded brake calipers.
The tuner fitted the SL with a new set of Y-spoke monoblock alloy wheels measuring 22 inches in diameter. Those are shod in mixed Hankook Ventus S1 Evo2 rubber measuring 295/30ZR22 at the front and 335/25ZR22 at the rear. Manhart offers additional chassis upgrades “according to customer requirements”, likely referring to a more aggressive suspension setup.
We don’t know the price for the 10 units of the SL 700 R Limited, but if there is enough customer interest, Manhart could come back with another SL-based tuning project in the future. Note that the upcoming Mercedes-AMG GT will be closely related to the SL, so it is safe to assume that it won’t go unnoticed by the Wuppertal-based tuner.
