All 2009 Hummer H3T models come with full-time four-wheel drive with a two-speed transfer case. All except the Alpha are powered by a 3.7-liter inline five-cylinder engine that makes 239 hp and 241 lb-ft of torque. The standard transmission is a five-speed manual, and a four-speed automatic is optional. Although the five makes decent power, it’s simply outmatched by the H3T’s near-5,000-pound mass, so acceleration is leisurely at best. Towing capacity is rated at 4,400 pounds when properly equipped, and EPA fuel economy estimates stand at 14 mpg city/18 mpg highway and 15 mpg combined with either transmission.

The Alpha features a 5.3-liter V8 (with 300 hp and 320 lb-ft of torque) mated to a four-speed automatic transmission. Towing capacity goes up to 5,900 pounds, and we’d expect its performance to be about the same as the H3 Alpha, which sprinted from zero to 60 mph in a relatively quick 8 seconds flat. With this engine, fuel economy drops slightly to a 13/16/14 mpg rating.

With a keen awareness of the growing consumer desire for more fuel-efficient vehicles, for 2009 Chevrolet offers an XFE (Xtra Fuel Economy) model, a two-mode hybrid, and now a six-speed transmission with manual shifting capabilities. The new Hydra-Matic 6L80 is available in Silverados equipped with the 5.3-, 6.0-, and 6.2-liter engines. It was first made available in crew-cab models and later will be offered in regular- and extended-cab models (except with the five-foot-eight-inch short bed) with 5.3- and 6.0-liter V-8s. The new transmission provides a lower rpm at cruising speed, improving fuel economy on the highway.

What better way to find out just how much of a difference the improvements have made than with a road trip? We requested an LT Crew Cab with the Z71 off-road package, 18-inch wheels with Bridgestone Dueler A/Ts, the 5.3-liter, E85-capable V-8 with 315 horsepower and 338 pound-feet of torque and Active Fuel Management, and the aforementioned optional six-speed automatic.

Leaving sunny Los Angeles, we were ready for a nearly 1400-mile journey to Northern California and the Sierra Nevadas and back. Once out of the metropolis, the trip consisted of mostly freeway driving, with some in-city travel, snow driving, and a windy canyon road thrown in for good measure.

The brawny, squared-off sheetmetal and wide stance can be unnerving at first in city traffic, but the Silverado’s excellent sightlines make its size easy to adapt to. Quick, accurate steering inspires confidence, and a smooth ride makes the Silverado a pleasant commuter. The LT came with a nicely appointed interior, albeit not the topline package found in the LTZ. Still, the seats remained comfortable despite the distance, and the XM Satellite Radio and auxiliary input jack kept us entertained for the duration of the trip. The center stack is still a ho-hum slab of gray plastic when the Navigation box hasn’t been checked on the order sheet, but the stereo and small upper glovebox–which requires two hands to open–were the only detractors from the otherwise nicely finished dash.

Because inclement weather was predicted, we unfortunately had to load the luggage in the cab rather than in the bed. However, the 60/40-split rear seat bottoms are easy to raise using one hand, which allowed us to stow the luggage on the cab floor. Folding the larger portion of the seat gave us a week’s worth of gear-stowing for three people behind the driver’s seat and still ample seating for a third passenger in the second row.

On the road, the Silverado was exceptionally pleasant to drive, providing a smooth ride–the suspension ably soaked up bumps and pavement imperfections. The steering was nicely weighted and communicative, and the manual-shift buttons on the column came in handy on long hills or when passing. Climbing up the narrow, windy Feather River Canyon, the Silverado handled nicely, never feeling underpowered or too wide for the road.

When the snow came, the Silverado remained unfazed. The Automatic four-wheel-drive setting handled slippery roads nicely, and putting it in 4-Hi four-wheel drive kept us trouble-free with deeper snow. Not once did the truck feel unsure or disconnected from the road.

Upon our return to Los Angeles, we had traveled 1364 miles (including a marathon 13-hour drive covering most of the length of California), from sea level to nearly 4000 feet and back. Along the way, we spent $148.71 on 79 gallons of regular-grade gas, averaging 21.7 gallons per fill-up at about $40 every 380 or so miles.

The 2009 Ford F-150 full-size pickup truck is available in three body styles: regular cab, extended cab (”SuperCab”) and crew cab (”SuperCrew”). Cargo box size choices vary as well: regular cabs come with a 6.5-foot or 8-foot cargo bed, while SuperCabs can have either of those or a garage-friendly 5.5-footer. The SuperCrew can have either the 5.5-foot or 6.5-foot bed. Reverse-opening rear doors are standard on regular and SuperCabs for easier cab access, while SuperCrews have four full-size doors.

No fewer than seven trim levels are offered: base XL, sporty STX, popularly equipped XLT, rugged FX4, luxurious Lariat, leather-saddle-inspired King Ranch and blinged-out, top-dog Platinum.

Geared toward commercial use, the bare-bones XL comes with 17-inch steel wheels, vinyl seating, an AM/FM radio, air-conditioning and not much else. The STX is similarly equipped but adds body-colored bumpers and grille frame, sportier wheels, a cloth 40/20/40-split bench seat and an upgraded sound system with a CD player and an auxiliary audio jack.

The volume leader XLT features chrome exterior trim (including the grille), an upgraded cloth interior, cruise control and full power accessories. The FX4 (4WD) shares its color-keyed bumper and grille styling with the STX and also features a towing package, 18-inch wheels, underbody skid plates, retuned springs and heavy-duty shocks, a leather-wrapped steering wheel, bucket seats with center console, a six-way power driver seat and satellite radio.

The Lariat trim offers an upscale ambiance with two-tone paint, a silver mesh grille insert, brushed aluminum and wood interior highlights, leather upholstery, 10-way power driver and passenger seats, heated front seats, power-adjustable pedals, the Sync multifunction voice command system, automatic climate control and a trip computer. Like the Lariat, the King Ranch has two-tone paint and the fancy grille, but it adds western saddle-inspired leather upholstery, a six-CD changer and heated/cooled front seats.

The new Platinum trim tops the line and features 20-inch chrome wheels, a unique grille design, monotone paint, chrome accents, premium leather upholstery, the heated/cooled seats and unique wood-grain accents.

Key F-150 options include the SFE (superior fuel economy) package that’s available on 2WD SuperCrew XL and XLTs with the 4.6-liter high-output V8. The SFE package includes the 5.5-foot bed, a 3.15:1 rear axle ratio and low-rolling-resistance tires. Other options include a premium Sony audio system, remote engine start, a navigation system, a back-up camera, a cargo management system, a stowable bed extender, reverse parking sensor, a rear-seat DVD entertainment system and a sunroof.

Aimed at those who work out of their trucks, Ford’s Work Solutions options include an in-dash computer with Internet access, a Midbox storage system (a lockable compartment located between the cab and bed) and a “Tool Link” system (which allows one to keep tabs on tools stored in the truck’s box via radio-frequency tracking).

While GM tries to keep itself in business, it’s also trying to launch a new set of hybrid pickupsfor the 2009 model year. Soon, GM will be letting journalists–including the car review experts at TheCarConnection.com–to drive the 2009 Chevrolet SilveradoHybrid.

GM says the new Hybridedition of the full-size pickup truck will be 40 percent more fuel-efficient in city fuel economy and 25 percent better in highway mileage.

The Silverado Hybrid will come in the four-door Crew Cab body, in either rear- or four-wheel drive. Outfitted with a 6.0-liter V-8 engine and GM’s version of the two-modehybrid system shared with the Chevrolet Tahoe Hybrid, the Silverado Hybrid will be capable of 500 miles of driving range. It will also be able to run on electric power alone, gasoline power alone or a combination of the two. GM’s Silverado Hybridpickup will also have cylinder deactivation technology, which turns off half the V-8’s cylinders to save fuel when it’s running under light engine loads. Chevrolet’s sister brand GMC will also get a hybrid version of their Sierra pickup.

Dual front and curtain airbags and stability control will be standard on the SilveradoHybrid. Minor aerodynamic tweaks help the Hybrid’s fuel economy; its battery pack is located behind the rear seats.

TheCarConnection.com will be driving the new Silverado Hybrid this month, with a full review yet to come. Stay tuned–in the meantime, find out more about the 2009 Chevrolet Silverado here at ChevyTruckReports.com, including extensive photos and pricing information.
