Mercedes-Benz B-Class PHEV



Introduction

Spacious, comfortable and agile, the Mercedes-Benz B250e is the plug-in hybrid version of the brand’s traditional B-Class model. A great all-rounder, the B250e aims to provide ‘electrically powered driving pleasure’ and everyday suitability and arrives as Mercedes rapidly expands its electric range. The plug-in hybrid is available in three AMG Line trims: Executive, Premium and Premium Plus.

Safety

The existing combustion engine B-Class scored a maximum five-star rating when Euro NCAP crash tested it in 2019, so we would expect similar scores from Mercedes’ plug-in version.

In terms of assistance systems, Traffic Sign assist comes as standard with the Premium Plus line and a substantial driving assistance package is also available with this trim at an additional cost. To further boost safety, the package includes features such as Active Blind Spot Assist, Active Distance assist and Active Lane Changing Assist. 

Design

The B250e takes a similar appearance to the traditional B-Class but adopts modern accents taken from Mercedes’ electric EQ range to set it apart. The long wheelbase and short overhangs give the B250e a dynamic silhouette alongside an eye-catching chrome-plated diamond grille. The Executive model sit upon 18” five-twin-spoke alloy wheels while the Premium Plus model adds a panoramic sunroof and memory function to the front heated seats.


The B-Class shares many styling cues with its smaller A-Class sibling with an understated exterior and classy, sophisticated interior made up of Artico man-made leather and microfibre upholstery. The wrap-around cabin seamlessly integrates across the dashboard, centre console and doors to create a welcoming feel for the driver. There’s a pleasantly surprising amount of space inside, too, with 405 litres of boot space.

Performance

The B-Class plug-in hybrid houses a 1.3-litre petrol engine paired with an electric motor to produce 218hp and 450Nm of torque over an automatic transmission. This results in a 0 – 62mph time of 6.8 seconds and a top speed of 164mph, which is limited to 87mph when using solely electric power.

A range of driving modes are available but driving in all-electric enables emission-free journeys for up to 42 miles and efficiency of up to 235mpg. You’d have to drive carefully and start the journey with a fully charged battery to achieve those numbers, but the MPV provides strong competition for SUV-shaped plug-ins. In terms of charging times, the lithium-ion battery can be charged from 10% - 80% capacity in just 25 minutes using a rapid charger, whereas a standard 7.4kW domestic wall box will achieve a charge of 10% - 100% within 1 hour 45 minutes.

Technology

As standard, the B250e features the MBUX infotainment system on a 10.25” display, which can be navigated via voice control or touch input and uses AI to predict the driver’s personal habits over time. You can also expect Android Auto and Apple CarPlay as well as wireless charging for full smartphone integration.

Invest in the Premium trim and you’ll also receive a 10.25” widescreen digital cockpit, augmented reality sat-nav, keyless entry and start, ambient lighting with a choice of 64 colours and an advanced sound system. The headlights upgrade to the Multibeam LED system when you opt for the Premium Plus line.

There’s also a choice of handy apps offered by Mercedes to make the running of your car that much easier. Mercedes me Connect provides a range of services to help you keep on top of maintenance, access more infotainment functions, display real-time traffic data, locate where your car is parked and notify you if your car is unlocked, allowing you to lock it via your phone.

Created specifically for the brand’s electric range, Mercedes me Charge provides access to a growing number of charging networks and makes easy work of paying; charging is simply authenticated by the app or your Mercedes me Charge card and you receive a monthly itemised bill for all your payments. 

Verdict

If what you’re looking for is a practical and efficient car for everyday driving situations, then the B250e is ideal. However, there’s nothing exactly ‘exciting’ about driving it. It’s comfortable, has all the necessary tech and serves up a smooth drive. As far as hybrid hatchbacks go, the B-Class B250e provides strong competition with quick charging times, impressive range and an app that makes owning an electric car as simple as it should be. Mercedes’ B250e will comfortably get you from A to B – and you can be reassured by the fact that you’re doing your bit for the planet in the process.
