Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.

Chevy and GMC trucks get CNG option pricing

Chevrolet and GMC have clued us in to pricing of the bi-fuel option for the 2015 Silverado and Sierra 2500HD CNG and 3500HD CNG pickups: it starts at $9,500; we're still missing the rest of the pricing inferred by the word "starts," however. If you remember from the Chicago Auto Show introduction, the 6.0-liter V8 puts out 360 horsepower and 380 pound-feet of torque when drinking gas, 301 hp and 333 lb-ft when inhaling CNG.
Chevrolet figures that a bi-fuel Silverado HD is worth $2,000 in savings if driven 19,500 miles on CNG and 7,500 miles on gasoline in the span of a year, a recoup rate easily attainable to high-mileage fleet owners. It can be specced on double- and crew-cab pickups with single rear wheels, not on dualies.
The 2015 Chevrolet Express and GMC Savana short-wheelbase passenger and cargo vans also get CNG options, starting at $10,825 for the three-tank system, and $12,090 for the four-tank system that can only be had on the cargo hauler. You'll find a bit more info on all of the permutations in the press release below.
