Not Interested: Ford Passes on General Motors' Nine-speed Transmission
Way back in 2013, General Motors and the Ford Motor Co. signed an agreement to collaborate on transmissions. The deal stipulated that GM would get access to Ford’s 10-speed automatic transmission, intended for rear-drive applications, if the Blue Oval could have the Hydra-Matic 9T50 nine-speed under development by The General for front-drive models — and everyone would save some money.
However, things didn’t play out as intended. Ford is now saying the nine-speed auto doesn’t provide enough of a fuel economy improvement to justify the added cost and weight of an extra gear. It won’t be using it, at least not in its current form. Instead, Ford engineers have decided to use a trio of transmissions with fewer gears for front-wheel-drive units.
2018 Volkswagen Tiguan Limited - The Old New Tiguan - Gets Extra Gears, More MPGs
Volkswagen of America is launching an all-new, second-generation, 2018 Tiguan in the summer of 2017. That’s the new new Tiguan.
But there’s also an old new Tiguan. Volkswagen is calling it the Tiguan Limited. Despite the major advances underpinning the new new Tiguan — it’s an MQB platform crossover with way more length, a third row of seats, and a dramatically different interior — the old new Tiguan will benefit from a significant update for 2018, as well.
The 2018 Volkswagen Tiguan Limited will send power to its front or all four wheels via a new eight-speed automatic, just like the new new Tiguan.
And with a new eight-speed automatic comes new fuel economy figures, something the old old Tiguan could have used years ago.
SAE Paper Summary Leaking 2015 Corvette's 8 Speed Auto Gets Redacted
It’s not known if the leak was intentional or not, but the summary of a paper initially published by the Society of Automotive Engineers, since taken down from the SAE site, says that a new eight speed automatic transmission, given the designation 8L90 by General Motors, will be introduced in the 2015 Corvette, on sale next fall. The all-new 7th generation Corvette is currently offered with GM’s 6L80 six speed automatic and a seven speed manual gearbox. The 8L90 is described as being designed for rear-wheel-drive applications and variants will likely be used in GM’s fullsize pickups and in rear wheel drive Cadillacs.
The 8L90 has about the same overall dimensions as the 6L80, and is said to be able to handle up to 737 lb-ft of torque. It has a shorter first gear for better launch acceleration, an overall ratio spread of 7.0 and three speed sensors for better shift response. Other benefits are said to be better fuel economy, improved performance and a quieter car with improved NVH levels.
