Mercedes E 300 E 2021: 7 Essential Specs And Highlights

The 2021 Mercedes-Benz E 300 e stands out as a benchmark in the plug-in hybrid luxury sedan segment, blending potent performance with exceptional refinement. This model pairs a 2.0-liter turbocharged petrol engine with a robust electric motor, delivering a combined 320 horsepower and seamless efficiency for daily commutes and long hauls alike.

Powertrain Excellence: Hybrid Synergy Redefined

At the heart of the E 300 e lies a sophisticated plug-in hybrid system. The petrol engine produces 211 horsepower at 5,500 rpm and 350 Nm of torque between 1,600-4,000 rpm, while the electric motor adds 122 horsepower at 2,000 rpm and 440 Nm of torque. Together, they unleash 320 hp and a staggering 700 Nm of torque, rivaling traditional six-cylinder diesels.

Acceleration is brisk, with 0-62 mph in 5.7 seconds and a top speed of 155 mph. The nine-speed automatic transmission shifts smoothly, enhancing the responsive feel across Eco, Comfort, and Sport modes. Real-world tests confirm its vigor, making overtakes effortless even under load.

The battery capacity has doubled to 13.5 kWh from previous models, promising up to 49 km of WLTP electric range. Without charging, it still achieves impressive economy—39.2 mpg over 311.6 miles, peaking at 42.2 mpg on motorways—far from the official 176.6 mpg but practical for hybrid users.

Design Evolution: Sporty Yet Elegant

Mercedes has infused the 2021 E-Class with a sportier, more youthful aesthetic. The elongated bonnet, signature grille, and multibeam LED headlights with Adaptive Highbeam Assist create a commanding presence. AMG Line variants add Night Edition styling for added flair.

Dimensions emphasize grandeur: nearly 5 meters long with a 1.6-meter wheelbase in coupe forms, it balances presence and maneuverability. Rear-wheel drive and optional air suspension contribute to composed handling, gripping corners confidently despite added battery weight.

Interior Mastery: Luxury Meets Technology

Step inside, and the cabin exudes prestige. The Widescreen Cockpit features twin screens, a new double-spoke steering wheel, and open-pore ash wood trim. Materials feel magnificent, with intuitive controls and ample adjustability for seats and wheel.

Space is generous upfront, though rear passengers in sedans note adequate but not class-leading legroom. Climate control whispers quietly, and the mild hybrid aids seamless stop-start without vibrations. Visibility benefits from a crisp backup camera, offsetting the narrow rear window.

• Key interior highlights:
• Twin-screen digital cockpit standard across trims
• Premium leather and wood finishes
• Electric seat adjustments via door-mounted controls
• Quiet cabin with minimal road and wind noise
• Advanced multimedia with voice and touch controls

Driving Dynamics: Comfort and Poise

The E 300 e excels on diverse roads. Air suspension (optional on test models) delivers high-class ride comfort, cushioning imperfections superbly at highway speeds. It glides over pavement with muted feedback, tracking straight and predictably.

Steering is quick and light for urban agility, though not feedback-rich. Braking is smooth but tests reveal longer panic stops, potentially improved with better tires. The added rearward battery weight introduces slight inertia in corners, yet overall composure remains strong.

In town, low-profile run-flat tires transmit some harshness, but freeways showcase its strengths: effortless power, low noise, and big-mileage prowess.

Technology and Safety Suite

The E 300 e boasts Mercedes’ latest tech. The virtual instrument cluster is standard, alongside a top-tier multimedia system with gesture controls. Driver aids include adaptive cruise control that adjusts for speed limits and curves, lane-keeping, and a comprehensive active safety package—most complete in the segment.

Steering wheel controls could be more intuitive, but the system maintains tight traffic gaps smoothly. Multibeam LEDs and LED taillights enhance night driving.

Practicality and Ownership Considerations

Trunk space accommodates the battery without severe compromise, though weight distribution affects handling subtly. Servicing costs are higher than average, and pricing positions it as premium—expect AMG Line Night Edition Premium Plus to command a fee reflecting its spec.

Electrification options abound: plug-in or mild hybrids for petrol and diesel, catering to varied needs. Standard equipment has improved significantly.
