I have a 2013 E550, it's been an excellent car. I'm not real happy with the direction MB has gone with the E class. You can't even get an E550 anymore. V8 and is faster even though it's 6 years older. The E63 still gives you a V8, but now it's a 4 liter engine, mine is 4.7 liters. 2014 is the last year for the W212 E550. That gets you the facelifted version, so it looks like the newer models on the outside. A 4.0L V8 is still pretty high displacement. I find it hard to believe your E550 is faster than an AMG E53. The current chassis is lighter than the previous chassis, and with turbocharging, it has more power. I'm skeptical of the 4 cylinder engines, but the 6 cylinder engines are plenty competent and can pack a bigger punch than the 8 cylinders of yesterday while being more fuel efficient. My E500W4 has a 5.0L V8 and it guzzles gas like nobody's business. Automakers need to avoid the gas guzzler tax on cars these days. 2,600. I know that it was not an insignificant expense when we purchased the car. My understanding is that Mercedes-Benz has successfully removed all of its non-12 cylinder vehicles from the gas guzzler tax as of the 2019 model year.
Thanks to the high compression ratio, the B‑Class F‑CELL can cover long ranges of up to 400 kilometres with the tanks full, over twice as far as the A-Class F‑CELL. If the tanks are empty, they can be filled simply and quickly in less than three minutes, thanks to a standardised refuelling system. A powerful high-voltage lithium-ion battery is used to store the power. It boasts an energy capacity of 1.4 kWh and is cooled via the air-conditioning system circuit. When it came to the battery for the B‑Class F‑CELL, Mercedes‑Benz drew on the experience garnered during the development of the lithium-ion technology for the S 400 HYBRID. Advantages of the lithium-ion battery include its compact dimensions and much superior performance compared with nickel metal hydride batteries (NiMH). The energy density is 30 percent higher than with NiMH technology; the power density 50 percent higher by comparison. Furthermore, high recharge efficiency and a long service life make the technology even more compelling. Mercedes-Benz has further enhanced the operating strategy of the electric drive with fuel cells for the B‑Class F‑CELL.
As the outside temperature plummets, the electric motor receives its electrical energy during a cold start both from the lithium-ion battery and from the fuel cell system as it "powers up". Battery power is sufficient as the outside temperature warms up; the fuel cell then comes on line later - depending on the power requirements. In drive mode, the energy management system constantly maintains the F‑CELL system in the optimum operating range. The lithium-ion battery dynamically smoothes out variations with regard to the electrical power required in the current driving situation. Whenever the driver brakes or as soon as they take their foot off the accelerator, the electric motor converts kinetic energy into electrical energy, which is then stored in the battery, using a process known as recuperation. While manoeuvring or on short journeys, the electric drive motor uses battery power. If the battery capacity is not sufficient, the fuel cell automatically kicks in. In a bid to ensure optimum efficiency and customer benefits, the intelligent drive management system decides whether the electrical energy is used from the lithium-ion battery, the fuel cell, or a combination of the two systems.
Five seats and a boot capacity of 416 litres make the B‑Class F‑CELL fully suitable for day-to-day and family use. The key components for the electric drive with fuel cell are optimally protected in the vehicle underbody, thanks to a space-saving design that also promotes a low centre of gravity. The generous interior space in the B‑Class is fully retained. Crash safety meets the extremely high standards associated with Mercedes, as the key drive components as well as the hydrogen tanks are placed between the axles. The B‑Class F‑CELL offers consummate driving pleasure and full day-to-day suitability - without local emissions. The innovative electric car also has a great deal to offer when it comes to equipment and appointments, including the bonamite silver special paint finish and exclusive 10-spoke light-alloy wheels. In the interior, leather upholstery, heated seats, automatic climate control and the COMAND system, as well as other features, ensure a high level of comfort. The dynamic energy flow display in the COMAND system display keeps the driver constantly abreast of the battery charge status, operating mode of the fuel cell system, as well as providing information on nearby hydrogen filling stations.
