The Mercedes-Benz B Class is a five-seat family hatchback with a raised roofline, a taller seating position and more cabin space than most cars of its length. It suits drivers who want room and easy access without buying into an SUV.
It sits in the smaller half of the Mercedes-Benz range, with a more upright body than a typical hatchback. At 4.42 metres long with a 420 to 445 litre boot depending on version, it stays easy to park while carrying a family's kit.
The choice is simple. One five-door body, a 1.3-litre petrol or a 2-litre diesel, both automatic and front-wheel drive, in Sport or AMG Line trim.

Manufacturer data for the versions we currently offer. Last updated 5 October 2026.
The B Class is a premium compact people carrier in everything but name: five seats, five doors, a high hip point and a tall roof, wrapped in a body just 4.42 metres long. This is the third-generation car, on sale in this form since 2022.
Reviewers consistently praise the cabin quality, the airy feel and the amount of rear legroom relative to the car's footprint, and they generally agree it drives more like a tall hatchback than a van-derived MPV. The common criticism is a firm ride on poor surfaces. Every version carries a three-year, unlimited-mileage manufacturer warranty.
Because the standard specification is unusually complete and the practicality is the point. Every B Class gets heated front seats, wireless phone charging, built-in navigation, a digital instrument cluster, Apple CarPlay and Android Auto, plus a hands-free tailgate and keyless entry and start.
Safety kit runs to autonomous emergency braking, blind-spot monitoring, lane-keep assist, automatic high beam, front and rear parking sensors and a rear-view camera. Euro NCAP awarded the car five stars, with 96% for adult occupant protection and 90% for child occupant protection.
Practical details matter on a family car: 420 to 445 litres of boot space depending on version, up to 1,530 litres with the rear seats folded, an 11.0-metre turning circle and braked towing of 1,600 kg. Adaptive suspension and privacy glass are standard too.
There are two engines, both automatic and both front-wheel drive, and neither plugs in. The petrol suits shorter, mostly urban mileage; the diesel makes more sense if your year is built around motorway journeys. Our petrol or diesel guide walks through the trade-off.
The petrol is the more powerful of the two on paper, with 161 bhp, 270 Nm and 0-62 mph in 8.4 seconds through a seven-speed automatic. Official economy is 44.1 to 47.1 mpg with CO2 from 136 g/km. A sensible pick for lower annual mileage.
The diesel trades a little power for pulling ability: 148 bhp but 320 Nm, an eight-speed automatic and 0-62 mph in 8.5 seconds. Official economy of 51.4 to 55.4 mpg is the draw, and its 445-litre boot is the largest in the range.
| Diesel | Petrol | |
|---|---|---|
| Boot | 445 litres | 420 litres |
| Power | 148 bhp | 161 bhp |
| Seats | 5 | 5 |
| 0–62 mph | 8.5 s | 8.4 s |
| Braked towing | 1600 kg | 1600 kg |
| Economy (WLTP) | 51.4–55.4 mpg | 44.1–47.1 mpg |
Two trims, and the gap between them is smaller than the names suggest, because the equipment you actually use every day is standard on both. AMG Line is mainly about a sportier look and a few comfort additions.
Sport is the entry version, with 17-inch 5 Spoke alloy wheels, artificial leather upholstery, climate control, a powered tailgate, heated front seats, wireless charging, hard disk navigation and smartphone integration with Apple CarPlay and Android Auto. The Sport is currently available from £568.14 a month.
AMG Line moves to 18-inch 5 Twin Spoke alloy wheels and sportier exterior detailing, keeping the artificial leather upholstery, and adds front sports seats and a heated steering wheel. Worth noting: it doesn't change what's under the bonnet. The AMG Line is currently available from £575.06 a month. Against the Sport, that is currently £6.92/mo more expensive.
If you're torn, think about wheel size and ride comfort rather than kit. Larger wheels usually firm things up, and this is a car most reviewers rate for comfort. Our guide to choosing your spec covers the questions we're asked most.
If the B Class is on your shortlist, the BMW 2 Series covers much the same premium-compact ground, while the Alfa Romeo Giulia takes a style-led saloon approach. Staying in the family, the Mercedes-Benz CLA is the sleeker alternative, and you can browse the full Mercedes-Benz range.
