Management at its Milton Keynes headquarters believe more customers could be brought into the brand through promoting the lower priced manual market.
Product manager Nick Williams said: “We’ve a huge market share in automatics but there’s massive growth opportunity with the excellent manual transmissions in C-Class and SLK.
Our marketing director has bought into it, and managing director Dermot Kelly has bought into it, so we’re looking at how it can bring more customers in.”
In C-Class, buyers currently pay a premium of £1,095 to £1,580 for the automatic transmission option.
The premium is from £1,480 and £1,610 for automatic in the SLK range.
May sees Mercedes-Benz begin promotions of its new branding, and marketing will use its flagship SL convertible, which has just been revised.
The three-pointed star emblem has changed slightly, but CI will not change at dealerships until their next planned refurbishment.
