The cabin uses leather and wood with multi-way power front seats as standard and dual-zone climate control. Air suspension softens the ride while noise-insulating glass keeps it quiet. Optional multi-contour seats add bolster and massage adjustment. Long-wheelbase cars gain more rear space and power rear seats.
Diesel V6 with combined consumption of 8.3-8.5 l/100 km.
ASSYST service system sets flexible intervals from driving style and conditions.
Standard kit includes ESP, ABS, Brake Assist Plus, PRE-SAFE and eight airbags.
No Euro NCAP crash test published for this model.
The 3.0-litre diesel returns combined figures of 8.3-8.5 litres per 100 km with a 90-litre tank. Urban use sits higher at around 11.6-11.8 litres while motorway running drops to 6.4-6.6 litres.
Servicing follows the ASSYST display that calculates remaining distance or days from actual use rather than fixed mileage. Oil and filter changes form the core of A and B services with brake fluid every two years.
Safety centres on PRE-SAFE that tightens belts and closes windows before impact, plus radar Brake Assist Plus, full airbag coverage and ESP. Active head restraints and seatbelt pretensioners are standard.
Living with the car means watching air suspension components and diesel particulate filter condition on higher-mileage examples. Regular ASSYST resets and fluid checks keep the 7G-Tronic and electronics reliable.
