Mercedes-Benz Introduces Large Sedan as Their First Plug-in Hybrid

With governments and even consumers requesting automakers to explore green technology, luxury cars offer the most viable place to create electrified powertrains. Luxury vehicles are typically sold at a high profit margin allowing the incorporation of new, exotic technologies to be performed without the limitations or sticker shock associated with electric cars trying to appeal to a growing market. That has been the key of success for Tesla Motors and the BMW i line is launching with the anticipation they can find a similar premium market for electrified cars. Taking their first step into the plug-in hybrid vehicle marketplace, Mercedes-Benz is all charged up with the newest variant of their flagship S-Class sedan.

Set to be one of the largest plug-in hybrid cars on the market, the Mercedes-Benz S550 Plug-in Hybrid will also be perhaps the most lavish vehicle to be chauffeured through zero emissions motoring. For up to 20 miles, the S550 Plug-in Hybrid will exclusively run off an electric motor. Storing the motor’s electric power, a lithium-ion battery unit is water-cooled and weighs a total of 251 pounds. Using a 230-volt charging station, the battery can be replenished in as little as 2 hours and 45 minutes.

The electric power source will be united with a 3-liter V6 biturbo gasoline powerplant. The gasoline engine of the S550 Plug-in Hybrid alone produces 329 horsepower and 354 pound-foot of torque. When combining the power units, Mercedes-Benz has rated overall output at 436 horsepower and 479 pounds-foot of torque. A modified seven-speed automatic transmission handles the momentum from both powerplants. Mercedes-Benz describes the electric/gasoline powertrain as a crossover of principles being effectively demonstrated in their Formula 1 cars this season. With a hefty curb weight of 2,310.1 kilograms (5,093 pounds), the S550 Plug-in Hybrid can muscle from 0 to 100 kilometers per hour (0 to 62 MPH) in 5.2 seconds. Top speed of the large sedan is electronically limited at 130 miles per hour.

Besides acceleration, the Mercedes-Benz S550 Plug-in Hybrid performs impeccably in reducing emissions. C02 (Carbon Dioxide) emissions from the powerplant over the course of 300,000 kilometers can be between 43 to 56 percent less compared to the equivalent vehicle running only on gasoline. The S-Class’ LED lighting also enhances the efficiency of the plug-in hybrid sedan. Even braking for the S550 Plug-in Hybrid is designed for maximizing energy recovery. The electric motor provides initial stopping force for the vehicle before the disc brakes complete the job.

Though the Mercedes-Benz S550 Plug-in Hybrid sedan has been engineered to be uncompromised in the delivery of low-cost, environmentally friendly driving, the electric/gasoline version of the luxury vehicle does present a trade-off. This compromise is arrived at when storing luggage in the rear cargo area. Trunk space for the Mercedes-Benz S550 Plug-in hybrid sedan is measured at 12.2 cubic feet. Compared to the conventional S550, the plug-in hybrid model loses 4.1 cubic feet of trunk space because of the additional electric powertrain components (Using US measurement).

A well-appointed luxury cabin is a heavily equipped space inside the S550 Plug-in Hybrid. Featuring leather upholstery, Mercedes-Benz has loaded the variant of the S-Class with dual-zone climate control, front seats with Memory package and a COMAND Online as standard. An air suspension system is also included on the S550 Plug-in Hybrid awarding the driver and passengers with a high-comfort ride. From comfort to safety, PRE-SAFE Collision Prevention Assist Plus warning system, Attention Assist and PRE-SAFE impulse is listed as high-end crash avoidance technology found standard.

Technology debuting on the Mercedes-Benz S550 Plug-in Hybrid is described as extended pre-entry climate control. The interior, seats, steering wheel and armrests can be preheated to a desired temperature through a computer or mobile device timed ahead of an occupant‘s entrance into the vehicle. Extended pre-entry climate control can also provide optional cooling to the seats of the S550 Plug-in Hybrid.

Plugging into Mercedes-Benz dealerships April of 2015, the electrified S550 will join the brand’s E400 Hybrid as well as variety diesel engined vehicles using BlueTec technology.

  Photo Credit: James Gilbert/Getty Images untitled On Wednesday of this week (May 5 th of 2021), NASCAR will formally present the sport’s newest Cup Series chariot. Originally called the Gen 7 car before adopting the moniker of the Next Gen car, the vehicle was initially planned to be part of the 2021 racing season but was pushed to 2022 due to the declaration of the COVID-19 pandemic in 2020 disrupting development as well as team finances to implement the Next Gen car. From the details already leaked about the Next Gen car, the 2022 Cup season is destined to deliver the biggest learning curve ever to drivers, team and fans.

Morbid Motoring History: Transaxle of James Dean’s Porsche 550 Spyder Up For Auction

Photo Credit: Porsche AG untitled More than 65 years after James Dean’s fatal highway crash on U.S. Route 466, a verifiable piece has surfaced of the vehicle involved in the ill-fated Porsche 550 Spyder the 24-year-old actor drove in his last moments of life. Through an online auction being held on Bring A Trailer , buyers with a desire to obtain a rather ghoulish gearbox. The Porsche 550 Spyder was one of the first purpose-built race cars assembled to establish a name of what was once a small sports car located in Stuttgart, Germany. A derivative of Porsche’s 356 production car, the 550 Spyder’s compact, lightweight stature (the 550 was in reference to the vehicle’s weight in kilograms) combined with a mid-mounted 1,500 cc flat-four engine proved almost instantly superior in competition. Entering competition in 1953 by Porsche, the 550 Spyder cemented much of the early on-track success for the brand including a class victory at the 1953 24 Hours of Le Mans. A total of 90

A New Four-Runner: Helio Castroneves Wins Monumental 2021 Indy 500

Photo Credit: Joe Skibinski/IndyCar untitled As race day for the 105 th edition of the Indianapolis 500 at the iconic Indianapolis Motor Speedway approached, a number of favourites emerged through the practices and qualifying session. Six-time IndyCar champion Scott Dixon topped the lists of many analysts after he captured the race’s pole position . Dixon’s #9 Chip Ganassi Racing’s Dallara-Honda posting the fastest time in Friday’s Carb Day practice only solidified the logic of picking the New Zealander to win. Other names favoured for having the best chances to drink milk in Indianapolis Motor Speedway’s victory lane included Colton Herta, Rinus VeeKay, Alex Palou and Alexander Rossi. Besides Scott Dixon, it is surprising to conceive after the 2021 running of the 500-mile greatest spectacle in racing that another more veteran name wasn’t immediately entered into top contention prior to the green flag. Unlike the COVID-19 delayed 2020 event that ran on August 23 in 85
