It's Fine To Start Off In Second Gear Only Sometimes

  It's Fine To Start Off In Second Gear Only Sometimes You might have heard that first gear isn’t necessary when accelerating from a stop. You might have heard that you can start just fine in second. Well, it’s okay to do that, but only sometimes. Jason Fenske of Engineering Explained is here to tell us when and why. Taking off in second in an automatic transmission, for example, is just fine. This is because an automatic uses a fluid coupling, so you don’t have to worry about wearing anything down while spinning the torque converter. In a manual transmission, however, things are a little different.

Today's Top Stories. 1. Why a 10 - Speed Transmission Actually Makes Sense . Ten gears seem like too many, but there's logic behind a 10 - speed transmission .

That 10 - speed automatic is the one that Ford and GM are both now gearing up to produce in their own plants. While each automaker will have their own version of the transmission , with unique software and other proprietary tweaks, the basic units are the same. Sometimes it makes sense for rivals to

On its face, a 10-speed transmission seems like a silly idea. It's just too many gears. Six, seven, or eight gears seem like more than enough to get the job done, so why would you complicate things by adding more. There's actually sound logic behind a 10-speed, however, as Jason Fenske of Engineering Explained details in his newest video.

To talk about 10-speed gearboxes, we must first talk about continuously variable transmissions, or CVTs, the car enthusiast's least favorite transmission. CVTs don't have fixed gear ratios-instead, they can constantly change their ratio to keep an engine at its ideal operating speed at all times. That means cars with CVTs tend to drone at a constant RPM when accelerating, which enthusiasts don't like, but that's great for efficiency and performance.

Ford Doesn't Want the Transmission it Planned to Borrow From GM

  Ford Doesn't Want the Transmission it Planned to Borrow From GM But GM still gets to use the 10-speed Ford developedAutomotive News reports that while GM has been happy to use Ford's 10-speed in several vehicles such as the Chevrolet Camaro ZL1 and Cadillac Escalade, Ford has yet to use GM's nine-speed. Instead, Ford developed a modified eight-speed version that will appear in the 2019 Focus, as well as several other 2019 models. It began work on two additional eight-speed automatics—one for performance use and one for smaller engines. The reason? GM's nine-speed didn't provide enough of a boost in fuel economy.

But, with Lexus and others using 8-speed trannies, it only makes sense that an automaker wants to Otherwise I think announcing a 10 - speed is mostly for show and a way to out-market the I think in the case of these transmissions , the primary goal is actually driveline feel and the secondary benefit

Here are the important stories you need to know. 1st Gear: Why Ford Isn’t Using GM’s Nine-Speed Automatic. Back in April of 2013, GM and Ford announced that they’d be working together to develop nine and 10 - speed automatic transmissions .

A CVT will always be more efficient than any other type of gearbox, but they wouldn't feel quite right in a performance or luxury car. So, to try to combine the best of both worlds, some automakers have added more gears to their automatics. In cars like the Lexus LC 500-which Fenske uses as an example-Chevrolet Camaro ZL1, and Ford F-150 Raptor, ten-speed gearboxes get pretty close to matching the performance and efficiency of a CVT, while preserving a traditional feel. It's not quite a have-your-cake-and-eat-it-too solution, but it's as close as we'll ever get.

And if you're still skeptical, consider this-Fenske averaged 29 MPG on a 400-mile highway trip in the LC 500, which is damn impressive for a car with a 471-hp 5.0-liter V8.

Mercedes-Benz axes four PHEV models to make way for EQ range .
Faster, more powerful EQ PHEV range starts this year withThe EQ unit fits a nine-speed automatic transmission with a clutch and an electric motor, and that transmission can then be paired with a number of engines. A 13.5-kWh lithium-nickel-manganese-cobalt battery (Li-NMC) powers the motor, that battery pack able to be charged in two hours on a high-speed charger. The third-generation e-motor provides 121 horsepower and 324 pound-feet of torque on top of the engine output. Pure electric range rises to an estimated 25 miles in the U.S. (31 miles in the U.K. on the European cycle), and electric-only top speed increases to 87 miles per hour, up from 81 mph.
