There is a lot to digest regarding the AMG E 53 Hybrid wagon’s plug-in hybrid powertrain and performance upgrades, so let’s dig in.
The heart of this PHEV is a turbocharged 3.0-litre inline-six engine paired with a 120-kilowatt electric motor and 21.2-kilowatt-hour battery. The motor makes 161 horsepower and 354 pound-feet of torque, and total system output, including the turbo six, measures 577 hp and 553 lb-ft (604 hp with Race Start active). Mercedes claims it takes as little as 3.9 seconds for this wagon to accelerate to 100 km/h.
Fully charge the battery and the E 53 wagon returns a Natural Resources Canada-rated 66 kilometres of electric range. It’s also rated at 10.5 litres per 100 kilometres combined in hybrid mode. We saw an indicated high of 70 km of range with a fully charged battery and an average of 10.3 L/100 km when exclusively using the gasoline engine.
Mercedes says it takes 20 minutes to bring the battery from 10% to 80% on a DC fast charger and 2.75 hours to juice it from 0% to 100% on a 9.6-kW AC home charger. For the first 400 kilometres of driving, we regularly recharged the AMG E 53 Hybrid after each trip (once to a full charge), and the car averaged 5.0 L/100 km with 52% of the distance traveled on electricity.
The list of AMG-enhanced hardware is long. It includes the AMG Speedshift nine-speed automatic transmission, a fully variable AMG Performance 4Matic all-wheel-drive (AWD) system, AMG Dynamic Select driving modes, AMG performance exhaust system, adaptive damping AMG Ride Control suspension, and rear-axle steering that can turn the back wheels up to 2.5 degrees.
Our test vehicle added the AMG Dynamic Plus Package, which includes AMG dynamic engine mounts, Race Start, an AMG electronic limited-slip rear differential, and an AMG high-performance composite braking system with larger 15.4-inch front discs and red, six-piston front calipers.
Collectively, this equipment transforms the E-Class wagon into an extraordinary real-world performance car, despite its hefty 2,435-kilogram (5,368-pound) curb weight. However, we’d skip the AMG Dynamic Plus Package simply because in our experience the brakes squealed, proved difficult to smoothly modulate in traffic, and were hard to trust when running the car hard in the mountains. Sometimes they would bite instantly to reduce speed. Other times they would not, forcing us to step on the brake pedal harder and more decisively. Such an inconsistent response to driver input is a distraction.
Otherwise, the AMG E 53 Hybrid Wagon covered ground like a guided missile. Its performance-tuned adaptive air suspension eradicated the potentially negative effects of the car’s extra electric motor and battery weight on the ride and handling. The ride is firm — as expected — but the car also shrugs off heaves, dips, divots, and cracks in the road as though they’re nonexistent.
Beyond that, the P265/35ZR21 front and P295/30ZR21 rear tires supplied outstanding grip in the twists and turns of one of our favourite mountain roads. However, in typical driving situations, particularly on highways, the road noise inside the cabin is excessive.
Switch into Sport or Sport+ mode, and the power is incredible. Accelerate hard from a stop and all four wheels rush the car forward without a hint of slip or struggle. We did not venture into speeds well beyond legal with this rocket of a wagon, but we imagine it would feel remarkably stable and buttoned down at such velocities.
For those who love driving, need a family car, and want to park something different in a multi-car garage, this AMG-tuned wagon is a compelling pick.
