The LARTE Performance kit developed for the G70 consists of seven exterior additions.

Reports suggest the existing M139 engine used in the SL43 will be phased out, largely because it won’t comply with upcoming Euro 7 emissions rules.

While Stuttgart prepares its own flagship, another German outfit has quietly been building something that could shake things up in a big way.

All vehicles planned up to 2030 will retain combustion power, although the company says it can pivot if needed.

Future M cars will continue to offer a manual option where possible.

Expect to see it make an appearance at a Formula 1 weekend and maybe even a surprise run up the Goodwood Hill.

It’s barely been used too, showing just 528 km (328 miles) on the clock.

This version of the GT marks the final evolution of the current generation, built strictly for circuit use and limited to just 67 units.

All parts are designed to mount directly onto factory fixing points, meaning no drilling or structural changes are required during installation.

According to the company, nearly every outer surface has been revisited, reshaped and, where possible, replaced with bespoke carbon components.

Just five units are planned with production to start in July this year.

For those worried about sound, Manhart fits a stainless steel system with four 115 mm outlets.
