GMC Sonoma: A Deep Dive into a Compact Legend

The automotive landscape is dotted with vehicles that carve out a special place in the hearts of their owners, and the GMC Sonoma, particularly its second generation, is undoubtedly one of them. Evolving from the popular GMC S-15 and Chevrolet S-10, this compact pickup truck quickly garnered a dedicated following, ranging from hardworking construction professionals and street-tough customisers to a vast legion of truck enthusiasts. Its initial appeal was rooted in a compelling blend of manageable size, remarkable versatility, and undeniable value, qualities that General Motors meticulously refined for its next iteration, aiming for nothing less than class-leading benchmarks.

For those needing a no-frills workhorse, the first-generation S-15/S-10 platform offered bare-bones models with a four-cylinder engine at an exceptionally low base price. But the platform's adaptability didn't stop there. Customers seeking more interior comfort could opt for an extended cab, while off-road adventurers had the choice of a robust four-wheel-drive system. This foundational success laid the groundwork for the more sophisticated and consumer-focused second-generation Sonoma, a vehicle designed with direct input from its future drivers.

The Birth of a Benchmark: Sonoma's Second Generation

General Motors embarked on an ambitious journey during the development of its second-generation S-trucks, employing extensive customer clinics to gauge progress, forecast market share, and fine-tune advertising strategies. Engineers were given concrete goals, quantifying class-leading benchmarks across an impressive 56 categories. This meticulous approach meant every aspect, from increased engine power to the precise tension of a door latch, was scrutinised and improved. The culmination of this hard work was unveiled for the 1994 model year, presenting a comprehensive line of pickups available in various configurations: short-bed, long-bed, or extended-cab/short-bed, all with options for two- or four-wheel drive. This strategic development ensured the Sonoma would not just meet, but exceed, the expectations of a diverse customer base.

Standard Features and Trim Levels

Beyond its contemporary styling, a significant draw of the second-generation GMC Sonoma was its impressive array of standard features, even on the base SL model. This wasn't merely a stripped-down utility vehicle; it came equipped with essentials that many competitors offered as costly extras. Standard fitments included power steering, anti-lock brakes, 15-inch wheels and tyres, an AM/FM stereo, and a practical rear step bumper. These features immediately elevated the Sonoma above many of its rivals, providing excellent value from the outset.

Stepping up to the SLS trim brought a host of aesthetic and comfort enhancements, transforming the Sonoma into a more refined vehicle. This included stylish wheel trim rings, colour-keyed front and rear bumpers, a matching grille and front air dam, and a subtle low body stripe for a cohesive look. Inside, the SLS boasted full-floor carpeting, two convenient 12-volt accessory power outlets, and highback bucket seats complemented by a centre console, enhancing both comfort and utility for the driver and front passenger.

For those with deeper pockets or specific needs, GMC offered further packages. The comfort-oriented SLE package provided additional luxuries, while the trail-blazing Highrider off-road package catered to adventurers seeking enhanced capability. The 1996 model year further bolstered the Sonoma's appeal, introducing sport suspension, four-wheel ABS for superior braking, and a highly practical side-access panel – effectively a third door for extended cab models, significantly improving access to the rear seating area. The sheer number of available configurations meant that a Sonoma could be tailored to almost any buyer's exact requirements, making it a remarkably adaptable vehicle.

On the Road: Performance and Driving Dynamics

To truly assess the evolutionary strides made with GM's redesigned pickup, a detailed long-term test was conducted. Our chosen test vehicle was a four-wheel-drive 1994 Sonoma Club Coupe. Starting from a base price of £16,613, it was equipped with a four-speed automatic transmission, air conditioning, a comprehensive power-equipment package, a tilt steering wheel with speed control, a locking rear differential for enhanced traction, an off-road suspension package, and heavy-duty trailering equipment. Crucially, the standard 4.3-litre/165-horsepower V6 engine was upgraded to the 'enhanced' version, delivering a robust 195 horsepower. This brought the total cost, including the rather trendy raspberry monochrome paint scheme, to £20,878 for a muscular, terrain-conquering machine.

Despite its off-road capabilities, our test Sonoma predominantly navigated paved roads. The eye-catching raspberry paint initially required some adjustment for the Michigan-based staff, but frequent compliments from other motorists soon made its unusual hue a point of pride. Inside, the well-appointed cabin immediately impressed. Drivers consistently praised the abundant storage space, the intuitive placement of switchgear and controls, and the convenience of the two auxiliary 12-volt power outlets, in addition to the standard cigarette lighter. Opinion on the front seats was somewhat divided; some staffers lauded their abundant comfort, while others felt they lacked sufficient support for longer journeys. However, there was universal agreement regarding the rear seats in the extended cab: they were best suited for short trips, small children, or perhaps a family pet, highlighting a common desire among extended-cab owners for more rear passenger space, ideally in the form of a bench seat – a clear indication of a future demand for a four-door crew cab.

For front-seat occupants, the increased body width and larger glass area, compared to the first-generation truck, significantly contributed to a more car-like driving experience. However, the pre-1995 airbag-free steering wheel's diameter was noted as being slightly too large to fully complete this 'driving a car' illusion. A driver-side airbag did, however, become standard equipment from the 1995 model year onwards, addressing this safety concern.

Engine Power and Fuel Economy

Powering our test truck was the torquey 4.3-litre/195-horsepower Vortec V6 engine, which provided impressive performance for a compact pickup. It propelled the Sonoma from 0 to 60 mph in a respectable 10.0 seconds, completing the quarter-mile in 17.1 seconds at 79.7 mph. While straight-line performance was slightly slower than a two-wheel-drive variant due to the 587-pound weight penalty of the four-wheel-drive system and larger tyres, the powertrain proved strong enough to tackle challenging mountain grades or effortlessly pull a 5500-pound trailer. Overall performance was highly rated by Sonoma owners, with over 90 percent describing it as above average. The Sonoma's class-leading V6 power, challenged only by the optional V8 in the larger Dodge Dakota, did come at the expense of fuel economy. Our 12-month average for the test vehicle was 18.7 mpg, though only seven percent of surveyed owners found this objectionable. Interestingly, some owners of four-cylinder Sonomas expressed regret at not opting for the V6, and even a few V6 owners voiced a desire for a V8, demonstrating the appeal of more power.

Ride Quality and Suspension Options

Historically, the term 'ride quality' was often an oxymoron when used in conjunction with light trucks. However, the GMC Sonoma proved to be a notable exception, offering a surprisingly comfortable ride in most on-road scenarios. GMC made it remarkably easy for buyers to configure the Sonoma's suspension to their specific needs, offering seven distinct setups split between two- and four-wheel drive. These options were given simple, descriptive names, eliminating the need for customers to delve into complex chassis dynamics like shock valving or spring rates. For our four-wheel-drive test truck, we could choose from options such as Solid Smooth Ride, High Payload, Off-Road, and Highrider. We opted for the ZM6 Off-Road setup, intended for recreational off-roading and heavy-duty trailering. While this setup proved more compliant than expected for such a purpose-built system, the Z83 Solid Smooth Ride option, designed for pavement and light off-road use with an emphasis on ride comfort, may have been more appropriate for our actual driving patterns. Surveyed owners clearly shared this satisfaction with their trucks' ride, as nearly 95 percent rated overall comfort as above average.

During a mid-year trip from Detroit to Los Angeles, the truck's car-like nature continued to impress the editors. Minor demerits were recorded for slow steering response, the tendency of unmanned seatbacks to flop forward during braking, and a somewhat bouncy nature on rough roads. Despite these small criticisms, the staff widely appreciated the Sonoma's many virtues.

Reliability and Maintenance

The long-term test vehicle's service history was typical for its class, involving routine oil changes and a few dealership visits for repairs under warranty. The first minor issue encountered was a sticking electric mirror remote switch, which was a straightforward warranty repair. A more serious problem necessitated towing the truck to the service centre: a failed electronic control module (ECM) was diagnosed and replaced under warranty, highlighting the importance of robust electronic systems. The demanding nature of high-usage stop-and-go traffic took its toll on the front brakes, which required premature replacement at 15,600 miles. While in the shop for this repair, the Sonoma also received rear brake adjustments, wheel rotation, and a front-end alignment, with the total cost for these services amounting to £402.13.

Customisation and Owner Satisfaction

The spirit of truck customisation was alive and well among Sonoma owners. A significant one-third of surveyed owners installed a bedliner and tonneau cover to protect their cargo beds, demonstrating a practical approach to vehicle utility. Hood-mounted bug deflectors were almost as popular, with mud flaps, aftermarket stereos, and tinted windows closely following in popularity. Most buyers found the additional features they desired readily available on the GMC options list. The high average purchase price of approximately £18,000 indicated that the majority of these trucks were equipped with a substantial array of optional equipment, reflecting buyers' willingness to invest in a highly personalised and capable vehicle.

Reader satisfaction with the Sonoma was exceptionally high, best illustrated by the consistently high marks the truck received across the board and the remarkably low percentage of complaints. Owners expressed genuine affection for their vehicles, with one North Carolina owner exclaiming, "This Sonoma is just a fantastic truck. It's a pleasure to drive." An enthusiastic electrician from Michigan even quipped, "If it were legal, I would like to have the 'GMC' letters in the centre of the grille light up," showcasing the deep connection owners felt with their Sonomas. This level of owner loyalty underscores the success of GM's efforts in designing a truck that truly resonated with its target audience.

Comparing the Sonoma's Strengths and Weaknesses

To provide a balanced perspective, here's a quick look at the Sonoma's key attributes:
