Performance & Engine Options Current W247 Generation

• The B-Class offers a range of efficient and peppy engines, including mild hybrids and a plug-in hybrid (PHEV):

Petrol Engines

• B 180 (1.3L Turbo, 136 HP) – Entry-level, good for city driving.
• B 200 (1.3L Turbo, 163 HP) – More power, still fuel-efficient.
• B 250 (2.0L Turbo, 224 HP) – Sportier acceleration (0–100 km/h in ~6.6s).

Diesel Engines

• B 180 d (1.5L, 116 HP) – Best for fuel economy (~4.5L/100km).
• B 200 d (2.0L, 150 HP) – Better torque for highway driving.

Plug-in Hybrid (PHEV)

• B 250 e – Combines a 1.3L turbo petrol + electric motor (218 HP total, ~40–45 miles electric range).
• Charges in ~1.5 hours (7.4 kW charger).

Electric Drive (Previous Gen)

• B-Class Electric Drive (2014–2017) – 28 kWh battery, ~140 km (87 miles) range.
• Slow charging by today’s standards (DC fast charging not available).
• Trim Levels & Equipment (Europe Market)

Style (Base)

• 17″ alloys, LED lights, MBUX dual-screen, keyless start.

AMG Line

• Sportier bumpers, 18″ wheels, AMG interior trim, flat-bottom steering wheel.

Premium Plus (Top)

• Augmented Reality Navigation, Burmester sound system, panoramic sunroof.

Optional Packs:

• Driving Assistance Plus (Semi-autonomous driving).
• Night Package (Black exterior accents).

Driving Experience

• Comfort: Softer suspension than A-Class, great for long trips.
• Handling: Not as sharp as a BMW 2 Series, but precise steering.
• Space: 385L boot (bigger than A-Class), rear seats fold flat.

Reliability & Common Issues

Generally reliable, but watch for:

• 7-speed DCT (Dual Clutch) – Occasional jerky shifts in early W247 models.
• PHEV Battery Degradation – Some reports of reduced range over time.
• Infotainment Glitches – MBUX can freeze (fixed via software updates).

Recommended Model Years:

• 2019+ (W247) – Improved tech and hybrid options.
• Avoid 2014–2016 Electric Drive (outdated battery tech).

Should You Buy a B-Class?

Yes if:

• You want a premium, practical family car.
• Prefer Mercedes comfort & tech over sportiness.
• Need a PHEV with decent electric range.

No if:

• You want a sporty drive (BMW 2 Series Active Tourer is better).
• Need a full EV (Consider the Mercedes EQA instead).

Hidden Features & Easter Eggs

“Hey Mercedes” Voice Assistant Tricks

• Say “Hey Mercedes, I’m stressed” → car activates climate comfort mode (softer air flow, seat massage if equipped).

Augmented Reality Navigation Hacks

• In cities, the live camera view (with arrows overlaid on the road) works better if you disable “3D buildings” in settings.
• Zoom in/out with two-finger swipe on the touchpad (not obvious).

Secret Boot Space

• Rear seats recline slightly (pull the strap twice).
• Dynamic LED Headlight Trick
• Hold the high beam assist + fog light button for 5 sec → enables “European mode” (wider beam pattern).

Best Tuners:

• RaceChip (Plug & play, keeps warranty if removable).
• Brabus B25 (Official Mercedes partner, +30 HP).

Handling Mods

• Eibach Pro-Kit Springs (-30mm drop, better cornering).
• AMG Line Brake Upgrade (Larger discs from A 35 AMG).

Exhaust Sound

• Remus Axel-Back (Deeper tone, no drone).
• Fake V8 Sound (MBUX can simulate AMG noise in Sport+ mode).

Hybrid & EV Secrets (B 250 e PHEV)

• “Battery Hold” Hack: Press ESP + Gas Pedal for 3 sec → forces ICE to charge battery while driving.
• Max Regeneration: Shift to “D-” (not just D) for stronger regen braking.
• Real-World Range: In winter, expect ~30 km (not 45 km).

Ownership Hacks (Save Money!)

Service Cost Cutting

• Oil changes can be done at independent shops (€150 vs. €300 at dealer).
• Reset service reminder manually: Hold Trip Reset + Call Button for 10 sec.

Cheap Insurance Trick

• Register as a “family second car” → ~15% lower premium.

Depreciation Avoidance

• Lease a PHEV (tax breaks in EU make it cheaper than buying).
• Sell before 100,000 km (diesel models drop hard after this).

Most Common Problems & Fixes

• MBUX Freezing → Hard Reset: Hold Volume Button for 30 sec.
• DCT Jerking → Software Update (TSB #LI54.50-P-065931).
• PHEV Charging Fault → Check fuse #58 in trunk (common failure).
• Worst Year: 2015 B 200 (W246) – Timing chain issues.

DIY Mods You Can Do in 10 Minutes

• Ambient Light Color Hack: Use Developer Mode to unlock hidden colors (YouTube tutorials available).
• Disable Start/Stop Permanently: Unplug sensor under passenger seat.
• Android Auto Full Screen → Enable in engineering mode.

Factory Secrets & Little-Known Facts

The Renault Connection

• The current MFA2 platform was co-developed with Renault (shared with Kangoo/Nissan Qashqai)
• The 1.3L turbo petrol engine (B 180/B 200) is actually a Renault-Nissan HR13DDT unit
• Mercedes modifies it with different turbos, mounts and software (power band is smoother than in Renaults)

Hidden Factory Modes

• Mercedes Benz B Class Transport Mode: Disables most electronics for shipping (activated by dealer)
• Can be manually enabled by holding hazard lights + brake pedal for 30 sec (useful for long-term parking)
• Dyno Test Mode: Disables stability control completely (hold ESP button for 10 sec while starting engine)

Weird Production Choices

• The rear wiper motor is identical to W204 C-Class units
• The PHEV battery cooling system shares parts with Tesla Model S pumps
• Early W247 models used the same door handles as the W222 S-Class

Ultimate Workshop Knowledge

• Torque Specs You’ll Never Find in Manuals:
• Wheel bolts: 130 Nm (higher than most Mercedes models)
• Battery terminal: 8 Nm (overtightening causes IBS sensor failures)

Fluid Capacities:

• Engine oil: 5.8L (despite being a small engine)
• DSG fluid: 7.2L (lifetime fill – but should be changed at 100k km)
• PHEV battery coolant: 9.3L (special G48 purple fluid)

Component Lifespans:

• Timing chain: 180-220k km (petrol)
• DCT clutch packs: 150k km (with proper maintenance)
• PHEV battery: 12-15% degradation at 100k km
