More Gears = More MPGs? Advanced Transmissions Critical to Meet CAFE

The manual gearbox continues to fade away.

by on Oct.10, 2014

The new Land Rover Discovery Sport will turn to a 9-speed gearbox to help boost mileage.

While the wider user of turbocharging and direct injection have been credited with boosting U.S. fuel economy to record levels, automakers are also scoring big mileage gains by turning to advanced transmissions, according to a new report by the Environmental Protection Agency.

New automatics using seven, eight and even nine gears are quickly becoming the norm, rather than the exception, along with even more exotic technologies such as double-clutch transmissions. While it’s not a hard-and-fast rule, the more gears the more the MPGs.

Stay in Gear!

But the latest trends are likely not to be good news for fans of manual gearboxes which no longer can claim to deliver both better mileage and improved performance, noted Aaron Hula during a presentation on vehicle trends at the EPA vehicle test lab in Ann Arbor, Michigan.


Chrysler Investing Nearly $400 Mil, Creating 1,250 Indiana Jobs

Factory to add new 9-speed automatic transmission.

by on Feb.28, 2013

Chrysler will add 1,250 jobs in Kokomo to build its new 9-speed automatic transmission.

Chrysler plans to invest nearly $400 million and create 1,250 new jobs at two plants near Kokomo, Indiana.

It’s the latest in a series of investments by the maker that has resulted in the creation of 8,000 more new positions since Chrysler emerged from bankruptcy in 2009. The new project also protects the jobs of another 3,400 jobs in Kokomo, a hub of automotive parts manufacturing.

“Chrysler’s future and the future of North Central Indiana are tied together, and that future has never looked brighter,” said Kokomo Mayor Greg Goodnight, following the announcement by Chrysler CEO Sergio Marchionne.

In his own comments, Marchionne pointed out that Kokomo is the only place in the world where Chrysler produces transmissions – though it does “outsource” some from suppliers like Germany’s ZF.


Land Rover Launching World’s First 9-Speed Automatic

But it won’t have an exclusive for long.

Land Rover will show off a new version of the Evoque equipped with a ZF 9-speed automatic.

Apparently, you can never be too rich, too famous – or have too many gears.

It wasn’t all that long ago when automakers were debating the need to go from four speeds to five — then six, seven and even eight. Now comes Land Rover which has announced it will demonstrate a new 9-speed gearbox in its wildly popular Range Rover Evoque during the upcoming Geneva Motor Show.

But the maker won’t have an exclusive for long. Chrysler CEO Sergio Marchionne recently confirmed his company will start offering a 0-speed automatic also produced by ZF in a variety of its front- and all-wheel-drive models, starting with the all-new Jeep Cherokee to be launched for the 2014 model-year.


Nein? Ja, a Nine-Speed Gearbox From Mercedes-Benz

How many gears is too many? Benz engineers say 9 is probably the limit.

by on Jul.19, 2010

The next-generation Mercedes-Benz S-Class could very well sport a 9-speed automatic gearbox.

The gearbox wars continue to heat up.  Mercedes-Benz engineers are trying to determine just how many transmission cogs are enough – and perhaps more importantly, how many the public will accept.

Numbers always seem to matter in the auto industry.  But in an era of increasing fuel-efficiency, it’s harder to put a positive spin on big displacement figures, and V6s and I4s are gaining more credibility as the fortunes of the V8 and V12 begin to fade away.

But it’s an entirely different story when it comes to gearboxes.  And where a 4-speed automatic might have seemed like plenty, just a decade ago, the numbers have more recently climbed to 5, 6, 7, and even 8.  Now, it seems, the Germans are pushing even higher.

New reports suggest that Mercedes is looking at a 9-speed option that would be used with its larger-displacement engines, something that could prove critical if the maker hopes to meet upcoming mileage standards in the U.S., and the strict new CO2 regulations coming in Europe, reports the British magazine

But don’t expect the automaker to begin work on a 10-speed once the 9 hits the road. Mercedes engineers contend – not surprisingly – that 9 is the upper limit when weighing cost, complexity, size and weight against greater efficiency.
