Summary


The Mercedes-Benz E-Class Cabriolet is a four-seat convertible, sitting above the C-Class Cabriolet and – since the S-Class Cabriolet has now ended production – is the largest convertible in the Mercedes family.

As the name suggests, the E-Class Cabriolet is effectively an open-top version of the E-Class coupé, which in turn is based on the regular E-Class executive saloon. The Cabriolet was launched in spring 2017, with a mid-life facelift arriving in 2020.

The E-Class Cabriolet is available with a range of petrol and diesel engines, as well as a petrol/mild hybrid and an unusual diesel/mild hybrid option. All models have a nine-speed automatic gearbox, while all-wheel drive is available is on some versions.

Mirroring the praise given to the E-Class saloon, the E-Class Cabriolet has been commended for its plush and refined interior, its ride comfort, sleek exterior and everyday practicality. Car concluded that The E-Class Cabriolet is “everything a four-seat convertible should be – pretty, comfortable and luxurious for sunny weather and decently practical for everyday drudgery too.”

While the Mercedes-Benz E-Class Cabriolet offers plenty of comfort, reviewers generally conclude that this drop-top is luxurious rather than sporty. Carwow commented: “It’s not much fun to drive through corners, but it excels at cruising gently with the roof down to enjoy the scenery.”

As of January 2024, the Mercedes-Benz E-Class Cabriolet holds an Expert Rating of 72%.

Safety rating


Independent crash test and safety ratings from Euro NCAP

No safety rating

As of January 2024, the Mercedes-Benz E-Class Cabriolet has not been crash tested by Euro NCAP. If and when it is put through its paces by Euro NCAP, we will publish the results here.

The E-Class Cabriolet may be based on the saloon of the same name but there are significant structural differences – mainly resulting from the car having no roof. As such, the Cabriolet does not inherit the saloon’s safety rating.

The Cabriolet is well equipped with standard safety technology shared with the E-Class saloon, such as autonomous emergency braking and emergency steering assistance. It also contains pop-up rollover bars behind the rear seats that can be activated in a fraction of a second, which are triggered if the car senses that it is tipping over.

Eco rating


Independent economy and emissions ratings from Green NCAP

No eco rating

As of January 2024, the Mercedes-Benz E-Class Cabriolet has not been lab tested by Green NCAP.

Reliability rating

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

The Mercedes-Benz E-Class family has a below-average reliability rating of 41%, according to warranty data provided exclusively to us by our commercial partner, MotorEasy. This score applies to both the current E-Class range (saloon, estate, coupé and cabriolet) and also to previous generations, which is worth considering if you are considering a used Mercedes-Benz E-Class.

Based on nearly 500 warranty claims, the average repair cost is just under £1,000 so a used car warranty is well worth considering if you own or are considering an E-Class. More than 30% of claims concern the electrical system, with an average bill of more than £500. Engine and gearbox faults are unsurprisingly the most expensive problems, and are not uncommon in the E-Class. Make sure that any warranty you are purchasing covers all of these problem areas.

Running costs for the Mercedes-Benz C-Class border on expensive, according to data provided exclusively to The Car Expert by our commercial partner, Clear Vehicle Data.

Fuel economy is disappointing for petrol models and around the market average for diesel-engined versions. Insurance costs likely to be high, though, based on data from the UK’s insurance group assessor, Thatcham Research.

Compared to the rest of the executive saloon sector, the car’s service and maintenance costs are pretty average.

The market for four-seater premium drop-tops is pretty small, with most car manufacturers having abandoned the market in favour of buiding ever-more SUVs instead. Mercedes continues to dominate the segment, with both the E-Class and C-Class Cabriolet models. It used to offer an S-Class Cabriolet as well, but that ended production in 2020 with no replacement expected.

The E-Class Cabriolet has more interior space, a higher specification and – inevitably – a higher price tag than the C-Class Cabriolet, which is a closer match to vehicles from other brands like the Audi A5 Cabriolet and BMW 4 Series Convertible.
