Auto News: RIP BMW Z4, GM’s New Truck Powertrain

BMW bids farewell to the Z4 roadster, and GM updates the powertrain for the 2017 Colorado and GMC Canyon in this week’s Auto News in :60.


It’s the end of the road for the BMW Z4.  The roadster is about to disappear from the automaker’s lineup after the the last one rolled off the assembly line in mid-August. The second-generation roadster arrived in 2009 and BMW sold 115,000 over the years.

But never fear roadster fans. BMW has a replacement in the works. It’s working on a new sports car platform with Toyota. It will used to build the Z4 successor and could be called the Z5. The platform will also reportedly be used to build the successor to the Toyota Supra as well.

The mystery roadster has actually already been spotted in road tests. You can see pics on the BMW Blog, which also reports a hybrid version could also be offered. Of course, that puts into question whether it would be a manual.

2017 Chevy Colorado, GMC Canyon Share New Powertrain

The Chevrolet Colorado and its sibling the GMC Canyon will arrive with a shared powertrain update this fall. They both get GM’s new 3.6-liter V6 paired to an all-new eight-speed automatic transmission. (It replaces a six-speed). The powertrain is good for 308-horses and 275 pound-feet of torque. Both numbers up slightly over last year – by slight we mean 3 more horses and 6 more pound-feet of torque.

The new powertrain combo actually don’t change overall payload and maximum towing capacity at all.

So what is the point of this new powertrain combo? We’ll let GMC explain it.

“The new 3.6L/eight-speed propulsion system offers stronger, more confident acceleration and smoother shift performance than the Canyon’s previous V-6/six-speed combination.”

“The 8L45 eight-speed also has a wider 7.0 gear ratio that enables a numerically higher first gear ratio — helping drivers start off more confidently with a heavy load or when trailering — and numerically lower overdrive ratios that reduce engine rpm on the highway.”

GMC says a lower engine speed has two benefits. It can reduce fuel consumption to enhance efficiency and makes the engine quieter.

The GMC Canyon also adds an off-road All Terrain X trim level.
