https://ift.tt/3wH4U9m Could Have Built a Quad-Motor Model S Beyond Plaid—Here’s Why It Didn’t

-

Elon Musk famously named the new tri-motor, high-performance variant of the 2022 Tesla Model S the “Plaid” because like the movie Spaceballs says, it’s the only step beyond “Ludicrous,” the previous top-dog in the Model S lineup. Well what if there is a step beyond Plaid and the cancelled Plaid+? According to a source at the company, there’s no reason why Tesla couldn’t make a quad-motor Model S if it wanted to.

Why Would Tesla Want to Make a Quad-Motor Model S?

Two reasons primarily: more power and more traction, which could potentially improve the Model S’ launch, and actually give it a sub-2.0-second 0-60 mph time without any gimmicks. According to the below cutaway, as the Model S Plaid is currently laid out it has two motors at the rear axle driving each rear wheel, and one at the front axle, arranged to primarily drive the front-right wheel.

These carbon-sleeved motors are identical, says our source, and are good for a total system output of 1,020 hp and 1,050 lb-ft of torque. That means each one produces around 340 hp and 350 lb-ft of torque.

Adding an additional front motor to the Model S would in theory boost horsepower to 1,360, and torque to 1,400 lb-ft, with the added weight of the motor (plus the drive force of the motor itself) possibly helping give the car better traction and performance.

Why Didn’t Tesla Make a Quad-Motor Model S?

As our source put it, Tesla simply didn’t feel the need to make a quad-motor Model S. The Model S Plaid’s dual-motor rear drive unit would fit on the front axle, but it would further shrink an already smaller frunk and make the car less efficient, while adding cost and complexity. Our source also pointed out that the Model S Plaid was already at the bleeding edge of the performance envelope, making it a riskier proposition to develop the automaker’s first-ever quad-motor system.

The Model S Plaid’s current tri-motor system is expected to be available on both the Cybertruck and Roadster, if either ever reaches production. Rivian appears like it will be the first automaker to market with a quad-motor system, which comes standard on its R1T and R1S pickup and SUV. GM isn’t far behind. The GMC Hummer EV Pickup will also feature a quad-motor powertrain when it goes on sale late this year.

Mercedes Benz F 1015 Luxury In Motion

The car's predecessor, the Mercedes-Benz W111 (produced 1959–1971) helped Daimler develop greater sales and achieve economy of scale production. Whereas in the 1950s, Mercedes-Benz was producing the coachwork 300 S and 300 SLs and all but hand-built 300 Adenauers alongside conveyor assembled Pontons (190, 190SL and 220) etc., the fintail ( German : Heckflosse ) family united the entire Mercedes-Benz range of vehicles onto one automobile platform , reducing production time and costs. However, the design fashion of the early 1960s changed. For example, the tail fins, originally intended to improve aerodynamic stability, died out within a few years as a fashion accessory. By the time the 2-door coupe and cabriolet W111s were launched, the fins lost their chrome trim and sharp appearance, the arrival of the W113 Pagoda in 1963 saw them further buried into the trunk's contour, and finally disappeared on the W100 600 in 1964. The upgrade of the W111 began under the l

https://ift.tt/3iMzCd8 the Army Now: Meet the Mil-Spec Citroën Ami

Okay, we admit it, our obsession with Citroën’s tiny Ami electric car is beginning to border on the unhealthy. We’ve already written multiple articles on this 8-hp French penalty box, and are eagerly awaiting its arrival to les Etats-Unis as part of the Free2Move rideshare fleet . Truth is, for people who do what we do, the Ami is the gift that keeps on giving. It’s comedy gold: silly-looking, ridiculously underpowered, and French. And now it seems it’s the Armée de Terre (ground forces) latest recruit. The French military has added four Citroën Amis to the motor fleet at its base in Istres in the south of France, which means perfect sense. How can any self-respecting republic protect the homeland without a micro-car that looks the same coming as it does going? Turns out that, much to our chagrin, the French army will not be marching into battle at the wheel of these voiturettes . Actually, the truth is both a bit boring and disappointingly sensible: The Amis will be used to

https://ift.tt/3A9sAoS Concept Recharge First Look: Fully Upgradable

The Volvo Concept Recharge heralds a new era for the brand, and maybe for the industry—one in which platforms are engineered for evolution. Lots of cars offer over-the-air software updates to keep customers engaged in, and in love with, their vehicles. But in the fast-moving automotive future, keeping a car’s technology current will require more than just freshened code. So Volvo envisions planning and packaging its cars with an expectation of periodic hardware updates as well. Volvo’s chief executive officer Håkan Samuelsson said, “If a car is to live for, let’s say 10 years, I don’t see computing hardware living that long. If you could upgrade maybe after half that time, you could give the car even more functionality in the last five years.” The sentiment was echoed by Mickey Kataria, the director of product management at—Volvo’s electrical architecture partner—Google. “I think we’ll have to introduce some notion of hardware upgradability,” adding this bit of context: “People alrea
