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).

General Motors’ focus on four brands – Buick,Cadillac, Chevrolet and GMC – indicates for the near term that light-duty trucks and SUVs will continue to be a part of the product mix, with new SUVs in the form of a Cadillac SRX crossover, Chevy Equinox compact SUV, and the GMC Terrain compact SUV among six new models announced for 2010.

While touting leading-edge design, technology, engineering excellence and quality in their ‘re:invention’ strategy, GM might see a glimmer of hope in a recent survey from J.D. Power & Associates, entitled “Automotive Emerging Technologies Study”, released this month. The study, which is designed to measure familiarity, interest and purchase intent for emerging automotive technologies, polls consumers before and after an estimated market price is revealed. For example, in the survey, 67% of the 19,249 respondents indicated that onboard navigation systems to guide them to the nearest Starbucks or other destinations were of interest.When the cost of a factory-installed navigation system was revealed at $1,600, interest dropped to 20% overall, while 45% of those who owned premium vehicles still chose the factory onboard systems versus lower cost off-board systems.

Mike Marshall, J.D. Power director of emerging technologies said, “Although the factory-installed options are considerably more expensive than an off-board navigation system, the price difference is not reflected in a proportionate decrease in consumer interest levels. Among consumers who express interest in both types of navigation system, seven out of ten indicate they would choose a factory-installed navigation system rather than an off-board version—despite the cost premium.”Other technologies fared about as well, and among consumers who listen to their portable digital music player in their vehicle, more than one-half use an auxiliary input jack, while approximately 20% use a wireless FM transmitter. Nearly 2/3s of consumers indicate that they would like the ability to listen to a portable digital music player through their vehicle’s speakers, while 27% express a desire to use a smartphone’s music capabilities in conjunction with their vehicle’s audio system.

Among consumers currently utilizing their vehicle’s Bluetooth functionality, initial interest for wireless connectivity in their next vehicle is 68%, compared with just 47% among those who have the feature but do not use it in their vehicle.Premium surround sound systems garner the highest interest rate among near-term vehicle intenders at 72%, while just 61% of consumers who plan on purchasing a new vehicle in two years or more indicate interest in this feature. “Consumers nearing the final phase of the vehicle purchase process are often more well-versed on vehicle options and features than those in the early stages of shopping, and likely have recently researched the available vehicle specifications,” stated Marshall, who added, “The increased familiarity of the possible benefits and conveniences of these technologies may lead to an increase in interest.”

How this bodes for an industry accustomed to making their profit on all the bells and whistles, and GM in particular with a plethora of trim levels and options, remains to be seen. In addition, how does the automotive aftermarket deal with consumers who are increasingly more interested in having the OEMs integrate these entertainment and connectivity technologies into the new vehicles? Time will certainly tell – but that’s oneluxury automakers don’t have, and a gamble they can’t afford to take.
