My year in EVs: 8 electrics that are changing the car industry

The year 2021 will go down as an inflection point in the auto industry’s transition to electric vehicles. It's when many much-anticipated models became reality. No longer sketches or sketchy prototypes, electric vehicles appeared from all corners with everything from the Lucid Air to Ford Mustang Mach-E changing how we think about transportation. I managed to drive a lot of them, and as I went through my notes, I realized IÂ’ve got a mini memoir of the seminal EVs of 2021. HereÂ’s my take on eight of them. Hummer EV Easily the most over-the-top EV I tested this year. The 1,000-hp super truck lived up to the hype with its domineering presence, stupendous power and simply being a reincarnated Hummer. I took it for a short spin on- and off-road at the General Motors Proving Grounds in Milford, Mich., and was impressed with the airy cabin, removable sky panels and expansive touchscreens. Yes, I crab walked, which felt like steering a pontoon boat, though I can see why it would be useful. Lucid Air Dream Performance The most beautiful sedan I tested all year, EV or otherwise. Unlike the futuristic Mercedes EQS — which is quite attractive — LucidÂ’s car is a blend of mid-century modern interior aesthetics and classic European exterior styling. When I walked up for my test drive, someone who IÂ’m pretty sure was comedian Jon Lovitz was sitting inside and taking it all in. As it sat in the valet of a hotel in a wealthy suburban enclave north of Detroit, the Lucid drew more attention than any of the Mercedes, Cadillacs or Lexus models passing by. The driving experience was enveloping. Starting at $169,000 for the Performance model (reservations are closed), the Lucid I sampled packed 1,111 hp and 471 miles of range. From the precise steering to the comfortable suspension, the dynamics were spot-on. It's a formidable product, and all the more impressive given itÂ’s LucidÂ’s first. Chevy Bolt EV The Bolt was the most pleasant surprise for me. It handled well, offered low-to-the-ground hot hatch dynamics and the steering was dialed-in. Adding a crossover variant for the new generation was a smart play. On a summer morning where I went to a first drive of the Ford Bronco at an off-road course, my hour-long commute in the Bolt was an enjoyable appetizer.  The Bolt was also my biggest disappointment due to its extensive recalls for fire risk. Ironically, I had the Bolt in my driveway when the initial recall went out for the previous generation (2017-19).

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

The Mercedes-Maybach Pullman Guard is a limo with a bulletproof vest

As fabulously plush as the Mercedes-Maybach Pullman is, there is a certain class of individual for which luxury is only part of the equation. Oligarchs, dictators, kingpins of questionable businesses, and probably some legitimate world leaders all love luxury, but they sometimes face some hairy commutes that demand a bit more protection. For them, the answer to their luxury car needs is the armored Pullman Guard. The Mercedes-Maybach Pullman Guard tops the line of S-Class Guard models that also includes the Mercedes-Benz S600 Guard and the Mercedes-Maybach S600 Guard. Like the non-armored Pullman it packs loads of leather, seats with practically infinite adjustability, and redundant gauges for rear passengers. It is also by far the longest S-Class vehicle available, stretching more than 40 inches longer than the next-longest Mercedes-Maybach. This tremendous length allows the Pullman Guard to have four-passenger seating in the rear, with two seats facing two others. It's the perfect place to sign treaties or entertain diplomats. Or, if foreign affairs aren't your speed, it would also be a convenient place to carve up territory, issue ultimatums to enemies, and intimidate dissidents. The Pullman Guard was developed alongside the standard Pullman, and because of that, the added armor does not sacrifice interior space. The armor does affect weight, though. The Pullman Guard weighs over 11,000 pounds. But, in return, the steel plates on the sides and floor, non-Kevlar-brand high-strength fabrics, and polycarbonate-backed windows protect occupants from bullets and explosives. Plus, the Pullman Guard features a twin-turbo V12 that produces 530 horsepower and 612 lb-ft of torque to haul the added ballast around. If a recognized authority is ordering a Pullman Guard, Mercedes also offers sirens, flashing lights, two-way radios, an emergency starter battery, and a loudspeaker system. These items are sure to be useful when trying to navigate seas of protestors in the streets. All of this extra protection will cost you though, and if you have to ask, you definitely can't afford it. But we'll tell you the price anyway. A standard Pullman will run around $500,000 at current exchange rates. For the Guard model, be prepared to shell out about $1.56 million. It's a steep price for sure, but for those whose pampered lives are in danger, it's probably worth it.
