Mercedes-Benz B-Class (2012 – 2018) Review

Mercedes-Benz B-Class (2012 – 2018) At A Glance

3/5
Honest John Overall Rating
The safety and practicality of the B-Class will be enough of a draw, even if Mercedes-Benz offers cars from within its own ranks that are more fun to drive.

+Loads of cabin space front and rear, excellent safety kit, good range of efficient engines, classy image.

-Firm ride on all models and worse on the sportier versions, inconsistent steering response, dash-top screen and infotainment system not the best.

Insurance Groups are between 13–27
On average it achieves 81% of the official MPG figure

The second generation of Mercedes-Benz B-Class aimed to be the premium manufacturer’s take on a small MPV or a beefed-up hatchback when it was on sale from 2012 to 2018. It’s a sort of ‘best of both worlds’ attempt of blending posh with practicality but without the huge price tag of the brand’s bigger SUVs. Mercedes isn’t the only brand to have tried this – the BMW 2 Series Active Tourer is a similar concept, as is the Volkswagen Golf SV (or Golf Plus) but it is a bit of a rarity.

The Mercedes-Benz B-Class is a development of the ideas originally thought up for the first generation of A-Class. This is why the B-Class has tall sides and single box styling, whereas the A-Class has developed into a more traditional premium hatch.

Those tall sides give the B-Class ample interior space for five, making it a plausible alternative to many MPVs and crossover rivals. Add in the appeal of the Mercedes-Benz three-pointed star badge, a large boot and strong build quality and the B-Class begins to build a case for itself.

There’s a choice of two petrol versions, which both use the same 1.6-litre turbo petrol engines in two different outputs. You can also choose from a 1.5-litre diesel or two versions of the 2.1-litre diesel and the most powerful diesel is also available with 4Matic all-wheel drive.

While the variety of engines and premium appeal of the B-Class will attract some to its ranks, this Mercedes-Benz does not offer much in the way of driving thrills. The handling is at best average for the class and the firm ride is necessary to stop the tall-sided B-Class from lolling about too much in corners.

Where the B-Class does regain ground is the amount of safety equipment supplied as standard with the car. All B-Class models have seven airbags, a Collision Prevention Assist Plus system to avoid accidents happening in the first place, plus a driver drowsiness warning. Mercedes-Benz also includes automatic child seat recognition to deactivate the front passenger airbag when a child seat is fitted.

There are three main trim levels on offer in the Mercedes-Benz B-Class, with SE, Sport and AMG Line. Given the market that Mercedes looks to appeal to, the standard level of kit is good even on the basic model. Even the SE cars got toys such as a reversing camera, leather substitute trim, a seven-inch display and active parking assist.

Sport adds more tech and some visual upgrades while AMG Line is the one that brings more in the way of a body kit and lowered suspension, for those of you that want your people carrier to have a degree of sportiness.

For many buyers though, the B-Class will be too expensive compared to rivals that make do without a Mercedes-Benz badge.

Mercedes-Benz B-Class (2012 – 2018) handling and engines

Driving Rating
This firmly sprung set-up of the B-Class is largely the result of Mercedes-Benz trying to make sure the car does not lean like a tacking yacht as it goes round corners.

Mercedes-Benz B-Class (2012 – 2018): Handling and ride quality

The B-Class is pitched somewhere between a full-blown MPV and family hatch. That’s a tough place to find yourself given how able so many other cars are that can do both. Unfortunately for the B-Class, this is not a line it treads with any great finesse.

For starters, the B-Class suspension always feels too stiff and unforgiving. It doesn’t matter whether you’re ambling through town or marking time along a motorway, the B-Class almost wilfully refuses to settle to a comfortable stride. The result is wearying combination of pitching and rocking motions that are far from ideal in a family car that is expected to carry children on a regular basis.

While Mercedes has achieved its aim and the B-Class wends its way through a bend with impressively little loll, it is a compromise we’d be willing to see moved more in the direction of ride comfort than outright handling ability.

If you opt for the Sport version of the B-Class, you’ll find both of the above traits accentuated to the point where the car is simply too uncomfortable on some of the UK’s more disparaging road surfaces.

We could forgive the B-Class some of its firm ride if it were a more sporting car or it made it up for it by being a joy to drive. Instead, Mercedes-Benz has further hampered the B-Class with power steering that does not deliver consistent, regular feedback. What you get is steering that is often too light in the straight-ahead position that then quickly transfers to being too heavy as you progress into and through a corner.

Mercedes-Benz B-Class (2012 – 2018): Engines

Luckily, all but the least powerful petrol and diesel engines are happy to work at lower revs and pull cleanly. The 122PS 1.6-litre in the B180 and the B180 d 109PS are fine around town and give good accounts of themselves for economy and emissions, it’s their more powerful sister motors that are preferable.

For petrol buyers, the B200 156PS version of the 1.6-litre turbo engine gives stronger acceleration with only fractionally less fuel economy but the same emissions.

As for the diesels, the B200 d is a good compromise between price, running costs, consumption and emissions. However, it’s hard to see past the B220 d that delivers a better turn of acceleration than the B200 d yet offers the same official 67.3mpg average economy and lower CO2 emissions.

If you choose the B220d, you also have the option of Mercedes-Benz 4Matic all-wheel drive. It shares its seven-speed dual-clutch gearbox with the front-drive B220d, but economy of 56.5mpg and 130g/km CO2 emissions versus the front-drive model’s 108g/km means you really need four-wheel drive to make it worth spending the extra.

 

Mercedes-Benz B-Class (2012 – 2018): Safety

The Mercedes-Benz B-Class performed well in its Euro NCAP crash test when it was first released, but as that was back in 2011 it’s worth bearing in mind that the tests have got somewhat stricter since then.

That said, it did as well as could be hoped under the contemporary conditions, scoring a maximum five stars and earning particular praise for its adult occupant protection.

The Collision Prevention Assist system was fitted from the start of the B-Class’s life and upgraded to a Collision Prevention Assist Plus system at the mid-life facelift in 2014. This meant the system could not only help with braking in the case of a front-on collision, but help mitigate the impact of a rear-end impact too.

Mercedes-Benz B-Class (2012 – 2018): Practicality

The driving position is good and affords an unhindered view to the front and sides of the car, while the raised position also lets the driver see over most other cars to gain early warning of any potential hazards.

It’s not so good when you look over your left shoulder when changing lane or reversing into a parking space as the thick rear pillars obstructs the view. To counter this, Mercedes-Benz supplies the B-Class with a reversing camera that shows its display in the dash-top screen.

Space in the rear seats of the B-Class is more than generous to accommodate three children, or even three child seats. A benefit of the tall sides of the B-Class is it also offers more than enough room for adults in the rear seats and headroom is never an issue.

Behind the seats is a 488-litre boot, which is much bigger than the class norm for small hatches. This can be extended to 666 litres with the rear seats slid as far forward as possible on their runners. The only downside here, perhaps, is the B-Class is strictly a five-seater where many of its MPV rivals offer seven seats.

Mercedes-Benz B-Class (2012 – 2018): Quality and finish

Even if the higher-set driving position has more in common with an MPV, the clear white-on-black dials, trio of central air vents and stereo and heater controls all tell you this is a car with premium aspirations.

Let your hand roam around the driver’s environment and every surface, button and control you come into contact with further enforces the idea that Mercedes-Benz has not skimped on the quality of the B-Class interior.

Mercedes-Benz B-Class (2012 – 2018): Infotainment

All of the dials are clear and uncluttered and the B-Class also comes with a dash-top display screen, which looks great. However, this screen is used to operate a lot of the car’s functions and this is achieved through a variety of menus, which can become quite trying when a simple press of a switch would have sufficed. It isn’t as easy to use as the equivalent systems in BMW or Volkswagen rivals.

The screen itself looks a little like it has been tacked onto the top of the dash – it sits high up rather than being fully integrated into the panels as it is on the likes of the Volkswagen Golf SV.

Mercedes-Benz B-Class (2012 – 2018) value for money

Value for Money Rating
The engine range in the B-Class is generally an efficient offering, with all the petrol engines claiming around 50mpg and the diesels around 70mpg.

Mercedes-Benz B-Class (2012 – 2018): Prices

When the Mercedes B-Class came off sale in 2018 the range ran from around £24,000 to about £32,000. The steps up through the range were fairly consistent, with the automatic gearbox attracting a premium of around £1600 and the steps between the trims all around £1000 to £1300.

Now, though, you can only get this version as a used car, and the B-Class’s desirability means that it has held onto its value fairly well. At three years old, it is still worth around 50% of its original price. This means that later models, at around two years old, will cost around £18,000 to £19,000. This brings you a low mileage – often as low as 10,000 miles or so – model with a decent specification.

Three-year-old models with higher mileage tend to be around £14,000 or so. Eight-year-old higher mileage models will set you back around £6000, heading up to around £8000 for ones that have covered fewer miles.

Mercedes-Benz B-Class (2012 – 2018): Running Costs

There is very little difference between the manual and automatic gearboxes when it comes to official figures, so economy needn’t be a factor when deciding which to go for. Those figures are on the old NEDC test cycle, though, so expect something around the 80% mark of that as a realistic figure – something around 50mpg for the diesels and 40mpg for the petrol.

The one to avoid if economy is important is the 4Matic all-wheel drive model, which takes a 20% hit on its mpg rating, with an official figure of 55mpg. You’ll have to really want all-wheel drive to want that, and given that go-anywhere ability is not this car’s main USP it makes it less of a worthwhile choice.

Model History

August 2011

New B-Class was officially revealed

Substantially more agile and efficient, but as comfortable and spacious as ever – the new B-Class from Mercedes-Benz is a winner on all fronts. The vehicle's lower height and more upright seat position provide for a first impression that hints at the compact sports tourer's dynamic credentials.

With a new four-cylinder petrol engine featuring direct injection and turbocharging, a new diesel engine, a new dual clutch transmission, a new manual transmission and new assistance systems, the front-wheel-drive car also rings in a new technological era for compact cars from Mercedes-Benz.

The 2012 B-Class is a typical Mercedes sports tourer, offering plenty of space combined with impressive dynamic performance as a hatchback saloon. The character lines of the exterior design indicate both of these attributes: the front and rear feature width-emphasizing design, with a wide, prominent grille and headlamps extending along the sides at the front while the rear end features a wide rear window, two-piece tail lights and a large tailgate with low loading sill.

Another Mercedes-Benz premiere is the twin wet clutch 7G-DCT dual clutch transmission in the B-Class. This transmission is extremely compact, extremely variable with regard to adaptation of the engine speed thanks to seven gears, features an electric oil pump for start/stop capability, shifts gear without any interruptions in tractive power and combines the comfort of an automatic with the efficiency of a manual transmission.

The new 6-speed manual transmission designed along similarly compact lines as a three-shaft transmission is a close relative of the DCT. Extremely easy gear shifting, low shift forces, low internal friction and a low weight are among its most important characteristics.

The modular "Energy Space" concept means that the new B-Class is already designed to accommodate versions with an alternative drive: appropriate interfaces in the body shell enable the main floor panel to be modified and a step to be produced for the versions with alternative drive. An underfloor compartment covering part of the area under the rear bench seat offers space for alternative energy accumulators.

Mercedes-Benz B160s and some B180s are fitted with OM 607 1,461cc belt cam Renault diesel engines. B180 BlueEfficiency and B200CDIs have OM 651 1,796cc chain cam Mercedes engines. B220CDIs have OM 651 2,143cc chain cam Mercedes engines.

December 2013

Four wheel drive B 220 4MATIC announced, available January 2014. Has 1,991cc 4 cylinder turbo petrol engine offering 184PS and 300Nm from a low 1,200-4,000rpm coupled to 7G-DCT dual clutch transmissiom and automatic four wheel drive. Top speed 140mph, 0-60 7.2, 42.2mpg combined, 156g/km CO2. Standard wheels 18" with 225/40 R18 tyres. Price £28,135, but 'Command' satnav not standard and extras can soon bump that up to £38,240.

December 2014

Mercedes-Benz launches revised B-Class

Externally, the 2015 Mercedes-Benz B-Class is distinguished by a redesigned front bumper with more pronounced air intakes either side of a wider grille and headlights with integrated daytime running lights.

The rear bumper has also been changed and now resides below new LED tail lights. Inside, the satnav map and vehicle functions are displayed on a bigger, tablet style 7" screen controlled by a knob on the console.

Entry level B-Class SE models come with 16" alloy wheels, comfort suspension and, reversing camera, Artico leather substitute trim,three louvre radiator grille, LED DRLs, LED tail lights, 7" display, Active Park Assist, air-condtioning, Collission prevention Assist Plus, iPhone connectivity, Bluetooth 7 airbags and leather covered multi-function steering wheel.

B-Class Sports get 17" alloys, twin tailpipes ambient lighting aznd rain sensing wipers.

B-Class AMG Line go to 18" alloys, bi-xenon headlights, Artico/Dinamica upholstery, AMG body kits and lowered Comfort suspension.

Petrol engines are a turbocharged chain can 1.6 with stop/start and 3rd generation direct injection in the B180 and B200.

The B180 CDI ECO and B180CDI share the same Renault based 1461cc belt cam engine, while the B200 CDI continues with 1796cc OM651 chain cam Mercedes diesel engine and B220 CDI with Mercedes 2143cc OM651 chain cam diesel.

All 2015 B-Class models benefit from new BlueEFFICIENCY technology making them up to 26% more economical than 2014 versions.

From Spring 2015 a completely electric B-Class using Tesla technology to extend its maximum range to 149 miles, at prices from around £27,500 (after the Government grant).

The B-Class Electric Drive operates in three-modes: Economy Plus for constant steady-speed journeys, which reduces the output of the motor to 85HP and top speed to 68mph. Economy mode reduces output to 135HP and Sport offers the motor’s full 182HP. The two Economy modes can be overridden and full power and torque accessed by the driver using the kickdown function.

The optional ‘Collision Prevent Assist Plus’ system uses radar-assisted recuperative braking to recharge the battery. Fully recharging the B-Electric via a 16-amp home wall socket takes around nine hours if the battery is empty. Using a 400-volt three-phase electricity supply the car can be recharged in three hours.

What to watch out for

10-06-2015:

Pre-Safe system of September 2012 Mercedes B180CDI failed. Warning 'pre-safe disabled' cam on and car had periodic and random loss of power, then the parking brake failed. Limped home and Mobilo recovered it to the MB dealer who "fixed" the problem with MB software updates. Yesterday it happened again. Pre-safe disabled and loss of power - on the motorway - and gave real cause for concern since it was like brake testing the cars behind (but with no brake lights) In fairness the parking brake still worked. Diagnostics show no fault, but apparently US forums contain many similar stories across different models with various suggested solutions.

29-08-2015:

Another reader suffered loss of pre-safe system on a 2010 Mercedes B Class 3 times , coupled with a loss of power, once back in March then twice in May whilst in Belgium on the Autoroute. The dealer did a software update which appears to have solved the problem.

29-07-2016:

Complaint of sudden surges at low speeds of around 15mph from 2016 Mercedes-Benz B200 petrol DCT auto. Dealer re-set software, but not cured. Seems to happen at the gearchange from 1st to 2nd.

19-07-2017:

Report of 2016 Mercedes-Benz B200 petrol 7G-DCT "surging" on upchanges from 1st to 2nd at low speeds and when driving downhill. Transmission software checked out. Could be a mass airflow sensor error or temp sensor error.

06-08-2017:

Report of 7G-DCT dual clutch tranmission problems with 2014 Mercedes Benz B220 Sport 4-Matic. First problem was a random surge in speed from the car when driven at low speed 5-10 MPH which took nearly a year to resolve with the replacement of the DSG clutch. It has now developed a new problem: intermittent failure to start.

17-08-2017:

Report of 2016 Mercedes-Benz B200d 7G-DCT failing to engage drive.

27-08-2017:

Report of clutch of 7G-DCT transmission of February 2016 Mercedes Benz B Class Diesel Sport failing at 18,000 miles. "Almighty judder and clang" in a public carpark. Dealer downloaded diagnostics onto a USB and sent to MB who instructed them to fit a new CVT transmission.

07-10-2017:

Report of Mercedes-Benz B Class electric owned since July 2015 on a PCP. Owner does 12,000 a year and has fully equipped his house with all the domestic electrical fittings for charging, plus Ecotricity and Polar chargecard for public recharge points, but has found that MB is discontinuilg electric B Class in 2018.

22-05-2018:

Complaint of 18,000 mile 2014 Mercedes B180d with 7G-DCT automatic transmission "sometimes hardly moves from standstill and it is very sluggish, but sometimes pulls away okay; also the gear changes sometimes run smoothly, but at other times rev up to 3000 revs before changing gear."

16-11-2018:

"Crunching" reported from 7G-DCT of fairly new Mercedes Benz B-Class.

02-03-2019:

Report of problem with Mercedes-Benz B-Class 132KW 250 E Sport EV suffering from a major problem whereby the 12 volt battery goes flat when the car is left on charge overnight. It seems that a charging relay clicks in and out continuously, drawing 15 amps or so from the 12 volt battery until it is completely depleted. With the 12 volt battery dead you cannot turn on the ignition, to get the traction battery to charge the 12 volt battery, so it is a dead start and an RAC call out. There is minimal experience of this car in the UK and MB UK is at a loss of offer an explanation or fix. (I suggested that the likely culprit might be the Charge Control Unit that has been giving trouble on BMW and VAG PHEVs.)

21-07-2019:

Report of problem with reverse gear of 2014 Mercedes-Benz B180 (petrol) 7G-DCT. Has happened 4 times within 2 miles from start of a journey when a warning comes up on the dash. Switching off ignition, waiting for 10 minutes then switching on again re-sets it. Local garage can find nothing on its diagnostics. If this is the wet clutch 7G-DCT then probably needs a transmissionoil and filter change that is scheduled at 3 years or 38,000 miles in VAG cars and Fords with wet clutch DCTs.

01-08-2019:

Report of dash message "visit workshop" in 2015 Mercedes-Benz B-Class E Drive B250e Auto Electric at 68,000 miles. Car runs normally: same range as normal (85 miles); same charging times. D ealer investigated and checked with the manufacturer and traced it back. They recommend a new battery (just under £5,000 fitted) and even though the drive-train and battery is now out of warranty and have said the manufacture will meet half the cost, so just under £2,500 to pay.

04-03-2020:

Reports of engine failure on 2013 B180 CDI which had a noisy main bearing after less than 23,000 miles. New engine needed, at a cost of £8000 (which includes an undisclosed goodwill payment from Mercedes-Benz UK).

What does the Mercedes-Benz B-Class (2012 – 2018) cost?
