Jalopnik Snap Judgment: This is a smart move by Chevy and GMC. If you give consumers some choice on fuel economy, more than likely they'll take it. Especially if it's at a low cost. That was the biggest problem we've got with the hybrid versions of GM's big SUVs — the added front end dollar figure destroys any possibility for recouping your monetary investment without driving the vehicle for tens of thousands of miles. But anyway, we're glad to see the General making any steps toward fuel economy gains at efficient prices — especially when mixed with the Tahoe's good looks — and without the garish stickering of the hybrid. Full press release below.

GM Full-Size Pickups And SUVs Deliver Better Fuel Economy And Same Great Capabilities With New 'XFE' Models

EPA-rated fuel economy increases to 15 city and 21 highway
Silverado and Sierra have the best aerodynamics in the class
Towing capacity on Silverado and Sierra increases to 7,000 lbs (3,175 kg)
2009 GMC Sierra Hybrid Delivers 25-Percent Improved Fuel Economy With All Of GMC's Professional Grade Capability
2009 Chevrolet Silverado Hybrid Delivers 25-Percent Improved Fuel Economy And Delivers Chevy's Rugged Capability

DETROIT - General Motors is building on the segment-leading fuel economy of its full-size pickups and SUVs with new XFE models of the 2009 Chevy Silverado, Chevy Tahoe, GMC Sierra and GMC Yukon. The vehicles use a combination of mechanical, aerodynamic and mass-reducing enhancements to deliver a 5-percent increase in EPA-estimated highway fuel economy and more than 7-percent improved mileage in city driving.

The aero enhancements make Silverado XFE and Sierra XFE models the most aerodynamic full-size pickups in the industry, with a "Best in Class" 0.412 coefficient of drag (cd). The pickups join the Tahoe Hybrid and Yukon Hybrid as the most aerodynamic full-size SUVs at 0.349 (cd).

The new XFE - Xtra Fuel Economy - models reflect GM's quick adaptation to an evolving market that remains a very important segment. They are available on 2WD vehicles equipped with the 5.3L V-8 and six-speed transmission. They achieve 15 city and 21 highway mileage ratings versus comparable non-XFE models' 14/20 ratings. Most importantly, the increased efficiency does not come at the expense of capability. Towing ratings for the Tahoe and Yukon are unchanged, while the Silverado and Sierra increase from 6,600 pounds (2,994 kg) to 7,000 pounds (3,175 kg) due to the new, six-speed transmission and high-capacity cooling package.

"We are pulling out all the stops to deliver a more efficient package for customers who need the capability of full-size pickups and SUVs and want the very best fuel economy," said Gary White, GM North America vice president and vehicle line executive for full-size trucks. "Our pickups and SUVs are already the fuel economy leaders of their respective segments, but our engineers knew greater efficiency was achievable. We fast-tracked the XFE models to get them into dealer showrooms as quickly as possible."

All models carry the XFE name badge and are offered in the LT trim for Silverado and LS and LT trims for Tahoe. Sierra XFE comes with SLE trim and Yukon XFE is offered with SLE and SLT trim. Most regular-production options for all models are available. Silverado XFE and Sierra XFE are offered in 2wd crew cab body styles only. Production begins this fall.

"In addition to the XFE models, GM already offers hybrid versions of the Tahoe and Yukon that achieve up to a 50-percent improvement in city fuel economy and coming in the first half of 2009 are the Silverado and Sierra Hybrids," said White. "These hybrid pickups offer up to 25 percent overall increased fuel economy and greater than 40-percent improved mileage in city driving."

XFE efficiencies

GM's more efficient full-size pickups and SUVs are powered by a 5.3L FlexFuel V-8 (LC9) engine that's built with a mass-reducing aluminum cylinder block and heads. It is rated at 320 horsepower (238 kW)* and 340 lb.-ft. of torque (461 Nm)* in Tahoe and Yukon and 315 hp/235 kW and 338 lb-ft/458 Nm in Silverado and Sierra. The engine is backed by a Hydra-Matic 6L80 six-speed automatic transmission (with high-capacity cooling on Silverado and Sierra).

A rear axle equipped with a fuel-saving 3.08 ratio is also standard on all XFE models. Lightweight aluminum wheels and low rolling resistance tires (with higher tire pressure) also are included on all models.

Other unique content and features for Silverado XFE and Sierra XFE include:

Soft tonneau cover (improves aerodynamics)
Extended front lower air dam (improves aerodynamics)
Lowered suspension and revised chassis tuning (improve aerodynamics)
Aluminum lower control arms (reduce mass)
Aluminum spare wheel (reduces mass)
Seventeen-inch aluminum wheels (reduce mass)
Automatic locking rear differential
Trailering package
Low rolling resistance tires
Other unique content and features for Tahoe XFE and Yukon XFE include:

Lowered suspension and revised chassis tuning (improve aerodynamics)
Aluminum lower control arms (reduce mass)
Aluminum spare wheel (reduces mass)
Eighteen-inch aluminum wheels (reduce mass)
Automatic locking rear differential
Trailering package
Low rolling resistance tires
The new XFE models reinforce GM's commitment to full-size truck leadership, which continue to the industry's best and deliver the fuel economy, capability, quality and choice that are important to customers.

The report also mentioned cancellation of a future Hummer product and the potential shuttering of a brand, though no concrete evidence has emerged to clarify whether the Hummer product cancellation and brand closure were one in the same (Hummer) or whether Hummer might be allowed to die on the vine while another weak brand, such as Buick, was closed outright or moved off-shore.

Acceleration: ****
The big 6.2-liter Vortec V8 gives you as much power as you need, whenever you need it. While we didn't have the opportunity to try to mash the pedal to the floor while towing, the 380 horses let us dart through traffic better than we expected we should have been able to, given the sheer size of this beast.

Braking: ****
Given the size, you'd expect long stopping distances, but the four-wheel disc brakes worked with aplomb, even when encountering the pressures of coffee-spilling stops that scared the bejeezus out of even our stony-faced road test editor. Seriously, we've just gotten those pants back from the cleaners — you know how many times it took for them to get the coffee stain out?

Ride: *****
Like a pillow. What? You didn't know the Yukon is the new Serta mattress? OK, not really, but the Yukon Denali took a series of potholes on I-75 like they were sidewalk cracks. This Huge-UV has the ability to take just about any standard byway or highway, regardless of disrepair, and make you feel like you're on the latest re-surfaced MDOT road.

Handling: **
The GMC Yukon handles like a beached whale. But, despite the Gigantor-like proportions, the turning radius was better than we expected. Still had to do a turn-and-backup on the road outside the ol' apartment building, but at least we didn't have to do it twice. So we guess there's that.

Gearbox: ****
The six-speed auto tranny may be good at helping the General wring that extra mpg out of the GMT-900's, but it's hopeless for feeling what gear you're in. Feel free to use the "+" and "-" buttons on the shift column to move up and down the gears. We didn't.

Audio: ****
Bose surround sound, XM Satellite radio, six-disc CD changer and the premium acoustic package. Nothing more than what you'd expect on a uber-equipped SUV.

Toys: ***
The power tailgate may be nice for the not-so-tall, but we wish it didn't force us to use it. Just another extra 15 seconds before we were comfortable pulling out of our parking spot. The rear DVD system would be great if we had kids in the back seat every day. But we don't and neither should anyone else buying this Giant-UV. Let's re-cap people — do not buy the GMC Yukon Denali as a soccer mom-mobile. And when are we going to get Xenon's GMC?

Value: **
At $55,750.00 the 2008 GMC Yukon Denali is more than some people put down to buy a house. Most people who need the room and size will probably find a non-Denali trim version will work out just fine for them and fulfill all their needs. And do it for $10,000 cheaper. This Truck-UV is only a value proposition if you're hauling lots of people and all their equipment. Period.

Overall: ***
It all comes down to what you're looking for. Frankly, although it works for us, there's very few folks it'll do the same for. And the Chevy Tahoe looks better, does the same thing, and costs much less money.

• 2008 GMC Yukon Denali, Part One

I think I'm now one of those people who "knows" I need one — at least some of the time. Since January, I've now spent so much time in the 2008 GMC Yukon Denali, I almost feel like GM should just hand over the keys. But I can't help it. The Yukon just seems to be a convenient choice whenever we've got the team in the Detroit area and we need a heavy hauler to lug our portly auto-writing frames around. Not to mention seemingly having more equipment in tow than is needed to put together a Top Gear segment.

Case in point. My most recent time spent behind the wheel of the new up-optioned Yukon was the end of last month — for a quick photo shoot with an upcoming vehicle being revealed at the New York Auto Show. With an extra two guys in town and their assorted video and camera equipment, that standard CUV's just going to end up getting stuffed to the gills. Not the Yukon.

As if hoisting myself into the driver's seat isn't enough, all it takes is a quick look out the front windshield (or into the rear-view mirror, across the cavernous double rear rows of seats and out the rear window) and you notice your vision falling well above the roofs of most cars in your line of sight. That's all you really need to remind you this ain't no pansy crossover you're rumbling down the road in.

Or you could just look at your gas gauge. Yeah, it's no 20 miles-plus per gallon CUV, that's for sure. Close to 20, maybe — we saw 17.8 MPG in mixed city/highway driving (EPA 13/19) — but definitely not 20-plus. But you're also not going to find any crossover on the market with a 6.2-liter V8 under the hood giving you 380 horses to play with and max torque of 417 lb-ft. But you'll need an engine that big with an animal packing 5800+ pounds unladen, like the Yukon truck-UV. Anything less would be pokey given this elephant of a vehicle's pack animal purpose.

It kills me when I see a MILF driving a Yukon or it's Chevy brother, the Tahoe, through the suburbs of Metro Detroit. That's because the Yukon, like any pack animal, isn't designed to pick the kids up from soccer practice or bring the groceries to your suburban home. Save those suburban tasks for something smaller, more pedestrian and definitely more pocketbook friendly at the pump. No, this camel of a cargo-carrier should only be used when you've got seven souls in the seats and all 45.8 cubic feet of cargo area behind the third row packed to the gills with equipment. Soccer moms need not apply.

I, on the other hand, feel like I need a vehicle like this. Well, at least I do when I'm not paying for it.

GM Premieres First Ever Fuel Cell, Hybrid SUV Fleet At The Oscars

LOS ANGELES - The red-carpet arrivals at the 80th Annual Academy Awards® on Feb. 24, will be transformed with advanced technology vehicles from GMC and Chevrolet. This fuel-friendly fleet - larger than any other assembled for a major awards show before - will enable Hollywood's hottest talent to enjoy stylish and environmentally friendly rides in one of more than 75 vehicles, including the GMC Yukon Hybrid, the zero-gas and zero-emissions Chevy Equinox Fuel Cell and the FlexFuel E85 ethanol-compatible GMC Yukon.

As the only ABC Network automotive sponsor of the 2008 Oscar® telecast, GMC and Chevrolet will bring hybrid and fuel cell technology to the forefront at the red carpet, and other Oscar Week events. The fleet continues GM's major strategic effort to provide "fuel-friendly" vehicles to the entertainment industry and spread the word about GM's environmentally-conscious cars, trucks and SUVs.

"GM's longstanding relationship with Hollywood and our strong commitment to bringing advanced technologies to market that will help diversify fuel sources and reduce vehicle emissions makes this the perfect time for GM to drive 'green' to the Oscars," said Dino Bernacchi, GM Director of Marketing Alliances and Branded Entertainment. "Our outreach to showcase GM's 'fuel-friendly' products will be increasingly evident in the entertainment industry in 2008 with presence at awards shows, film festivals and special events, as well as a heightened product placement effort in movies and television."

GM's ramped-up efforts to drive Hollywood "green" began with "fuel-friendly" vehicles at the 50th Annual GRAMMY Awards and 39th NAACP Image Awards. Chevrolet is also reaching out to the next generation of tomorrow's influencers with the first-ever "Chevy Rocks The Future" event on Feb. 19. GM already provides the largest "fuel-friendly" product placement fleet to Hollywood producers and directors with nearly 20 different vehicle types.

Later this quarter, Chevrolet will hand over the keys to Chevy Equinox Fuel Cell vehicles to major entertainment celebrities for everyday use as part of its Project Driveway program - an effort by Chevrolet to move fuel cell technology from the laboratory into consumers' driveways.

The GMC Yukon Hybrid is the industry's first full-size SUV hybrid. No other hybrid can offer the fuel efficiency and full-size SUV performance including seating for up to 8 passengers and 6,200 lbs. maximum towing.

The 2008 Yukon Hybrid boasts vastly improved fuel economy over its gasoline-only sibling. Two-wheel drive models, for example, deliver 21 mpg in the city, a 50-percent improvement over its 5.3L non-hybrid sibling and comparable to the much-smaller 2.4L-equipped Toyota Camry sedan, according to figures obtained from www.fueleconomy.gov.

This year's Oscars will be the first major awards show where a fleet of fuel cell vehicles will provide transportation for celebrities. The Chevy Equinox Fuel Cell electric vehicle is a zero-gas, zero-emissions vehicle that makes no compromises, achieving 0 to 60 mph in 12 seconds, 236-lb.-ft. of instant torque and top speed of about 100 miles per hour. It seats four, sports 32 cubic feet of cargo volume for everybody's gear, and has a range of approximately 150 miles per fill-up based on the new 2008 EPA adjusted measurement. The Equinox Fuel Cell also features full four-wheel ABS for controlled, confident stopping.

Aside from its dramatically different propulsion system, the Equinox Fuel Cell looks and drives much like a production Chevy Equinox (a small SUV).

In addition to the GMC Yukon Hybrid and Chevy Fuel Cell Equinox, a select number of FlexFuel E85 ethanol-compatible Yukon SUVs will drive to the red carpet. Biofuels such as E85 ethanol have tremendous potential to help offset the world's growing energy demands, and General Motors offers more FlexFuel E85 ethanol-capable models than any other brand, with 2.5 million FlexFuel E85 ethanol vehicles currently on the road. FlexFuel E85 ethanol vehicles can run on either gasoline or E85 ethanol - a blend of 85 percent ethanol and 15 percent gasoline - or a combination of both.

The Academy of Motion Picture Arts and Sciences (AMPAS) will present the 80th Annual Academy Awards for outstanding film achievements of 2007, on Sunday, Feb. 24, at the Kodak Theatre at Hollywood & Highland Center®, televised live at 5 p.m. PST/8 p.m. EST by the ABC Television Network.

On Monday, we got a call from our friend Nick, who - thanks to a Blackberry and a spirit of adventure - is the first U.S. customer to take delivery of his very own Smart. The company even gave him a plaque to commemorate the occasion. It credits him in part with, "Initiating a revolutionary change in the way Americans think about transportation."

We do need to change the way we think about the Smart. It is safe. Mercedes developed the original version with the goal of making it as safe as their E-class. Bookended by crumple zones, a steel roll cage surrounds the occupants. Not only does that cage resist deformation in even the most severe impacts, in a crash it will actually activate the crumple zones on larger cars, using their in-built protection to cushion the Smart's occupants, too. It also comes with the full retinue of airbags.

It feels safe, too. The size defines the driving experience, but not in the way you might expect. Rather than feeling intimidated in traffic, you feel empowered. Gone is the need to take responsibility for an acre of SUV on a crowded road. Present is the freedom to move down that crowded road as you see fit. Congested urban streets and crowded highways stop feeling claustrophobic and start feeling easy. It's quick to turn, yet feels more stable than most vehicles twice its size.

It's not too small inside. I'm 6'2" and I couldn't reach the steering wheel with the driver's seat all the way back. Compare it to the front cabin of big SUVs like, say, GM's Yukon / Escalade / Tahoe and the Smart is positively spacious, thanks to it's airy design and upright seats.

It's not Green. The problem is, the Smart isn't that smart. The 1-liter, 70bhp engine has to work hard, so it only averages about 38mpg. Less if you drive fast. In Detroit, Mercedes showed off something they called the Micro Hybrid. It wasn't a hybrid at all, but switched itself off below 5mph, resulting in urban fuel consumption of 58mpg. The Smart desperately needs that technology, or a least a diesel engine.

It's not gay either. Sure, if you live in a doublewide and think Budweiser is the height of sophistication, then the Smart probably doesn't fit your Trans-Am ideal of what a manly car should be. But neither does it carry the level of campness of say, a Volkswagen Beetle. Rather, in traffic, the Smart's driver looks, well, smart.

So the Smart is a more complete, practical car than most people assume it to be - but that's also its biggest problem. Most people who stop to ask what it is think it's electric or at least a hybrid. It isn't. Neither is it cheap. The Fortwo Passion Cabriolet pictured here costs $18,500. It'll still get caught in traffic jams. Look at the Smart as a practical car that's easier to use in an urban environment than anything else, and you'll be happy. Look at it as fundamentally altering the way Americans think about transportation though, and you'll be disappointed.

Installing the hybrid powertrain meant giving the Tahoe a distinctive look. Since the system adds on around 400 pounds of curb weight, GM engineers set about removing mass from other places. Aluminum replaces steel at the rear lift-gate, hood and bumper. An all-new stamping of the hood ties into modified front-end features to increase aerodynamic slip. Even the running boards have been redesigned to help the Tahoe slide thorough the air with less effort. Further mass was extracted from the seats, wheels and tires.

Starting the Tahoe was standard turning-the-key type business. As in Toyota's Hybrid Synergy Drive system, the screen normally occupied by the navigation system now features animated graphics displaying what percentage of which mode is powering the vehicle. There's also a simpler economy gauge with a needle left of the speedometer to prevent driving mishaps while gazing at the fancy display.

Also as in full hybrid systems like Toyota's and Ford's, a feather foot will keep the Tahoe in full electric mode. A leaden foot brought on the familiar Chevrolet V8 kick, which scooted the monster into motion as expected. Some quick regenerative braking brought the Tahoe to a stop, and full autostop mode silenced the behemoth in standstill Santa Monica, California traffic.

The usual engine-driven accessories have been replaced by all-electric versions, so power steering and AC work while the Tahoe is running in both electric-only and autostop mode. Besides hanging out in California, the Tahoe and GMC cousin Yukon have both been run up to the cold of the Great White North for frigidity tests and down to Death Valley for a scorched-earth exam. As GM staff pointed out, the core hybrid technology behind the two-mode transmission had also been torture tested in the running gear of GM-Allison public transit buses before being incorporated into the larger GM hybrid plan, of which the two-mode Tahoe is just one part. The other part is the Volt plug-in dealy.

Cramming hybrid technology into the existing Tahoe body without having to tear up the base platform or the Arlington, Texas plant where the Tahoe will be built has helped streamline production. GM expects to have the two-mode system installed in showroom Tahoes and Yukons available this this Fall as 2008 models. GM says the system improves city mileage by 40 percent. GM's has yet to reveal highway improvement figures, though had said the composite highway target was 25 percent. Engineers say they're hoping to best that highway figure when the official numbers are released.

Channeling the power according to driver demand is the HOS, or Hybrid Operating System. By joining the HOS and two-mode transmission with existing engines, GM plans to make hybrid technology across the entire model lineup. Theoretically there are no limitations as to which engines can bolt up to the two-mode transmission, from full size trucks to smaller Saturns. A turbodiesel or even flex-fuel engine could married to the transmission, with the HOS sorting it all out. Such modularity could give GM an edge when it comes to hybrid line expansion. Pricing has yet to be announced, but we were assured the Tahoe and Yukon Hybrids would not be the most expensive models on the showroom floor. Still, we're saving our change for the Hoss Cartwright Bonanza Edition Yukon.

GM's Week of the Hybrid may have been punctuated by the plug-in announcement ("we're working on it"), but the most significant hybrid in the General's stable over the short term is the GMC Yukon, which it unveiled at the LA Auto Show earlier this week. The 2008 model, whose release date is still a year away, will feature the GM/DaimlerChrysler/BMW two-mode hybrid-drive system, supporting a Vortec V8 (FYI: the two modes are slow and fast). The system allows electric-only power at low speeds — comparable to Toyota's hybrids — as well as cylinder deactivation and various cam and valve tweaks to increase the small-block's efficiency. Some body pieces have been redesigned to reduce weight. All told, the General is expecting a 25% improvement in fuel economy over a comparable gas-only model. In a pinch, it can also tow 6,000 pounds worth of solar panels back to the underground eco-shack in Taos. That's what we call win-win-sort-of-win. – Mike Spinelli

Why you shouldn't buy this car:
The Tahoe looks better, and the Escalade has more cachet. 13 miles per gallon in the city. Fifty-two grand is a whole heap of change for a glorified family car - if you really want to haul the kids, buy a Sprinter Van.
