2020 RAM 1500 Reviews Summary

A full redesign for the 2019 model year left a significant bit of tech on the table for the increasingly popular Ram 1500 pickup truck: the EcoDiesel 3.0-litre engine. Ram was once the only option for a half-ton diesel pickup, but emissions certification problems resulted in Ram pulling the diesel engine a few years ago. The engineers at Ram have been hard at work updating it ever since. Although the EcoDiesel wasn’t ready for 2019, it’s now available for any 2020 Ram 1500 trim, so it seems it was well worth the wait. With 80% new parts, the EcoDiesel's improvements to power, efficiency, and delivery all mean that Ram is fighting hard to change minds about North America’s least-loved engine type.

2021 GMC Sierra 1500 Reviews Summary

GMC is the “professional grade” brand at General Motors, but that’s just marketing mumbo jumbo. The 2021 GMC Sierra 1500 is the same thing as a Chevrolet Silverado 1500, but with different styling and a handful of unique features, like an optional carbon-fibre composite cargo bed. This year, GMC makes several changes to its full-size light-duty pickup truck, none of them earth-shattering. This remains a fundamentally appealing truck in need of attention to the details.

2020 RAM 1500

8/10

2021 GMC Sierra 1500

6/10

The 2020 RAM 1500 was a standout in the truck market, known for its iconic design and impressive sales figures. Despite the presence of the older Ram 1500 Classic, the redesigned model managed to outsell competitors like the Chevrolet Silverado. The RAM 1500 boasted a bold grille design that had been a signature feature for decades, setting a trend that others were just beginning to follow. Starting with the Tradesman trim, the RAM 1500 offered a range of features, including 18-inch steel wheels, vinyl upholstery, and a 5-inch touchscreen with the Uconnect infotainment system. As buyers moved up the trim levels, they could enjoy additional features like air suspension, dual-zone climate control, and advanced infotainment options. The RAM 1500 Rebel catered to off-road enthusiasts with its aggressive profile and enhanced capabilities, while the Laramie and Longhorn trims added luxury touches like leather upholstery and advanced tech features. The top-tier Limited trim offered premium amenities, including a 12-inch touchscreen and advanced safety features, making it a versatile choice for those seeking both utility and luxury.

In contrast, the 2021 GMC Sierra 1500 was known for its distinctive styling and upscale Denali trim level, which was often compared to luxury brands like Mercedes. The Sierra AT4, priced at $78,938 Canadian, was the off-road-ready version, featuring a factory-installed suspension lift, off-road suspension, and unique design elements. The AT4 CarbonPro Edition Package added a carbon fibre composite cargo bed and a MultiPro Audio System for the tailgate. The Sierra's interior, while functional, was criticized for its use of black plastic and lack of luxury feel, despite features like heated and cooled seats and a heated steering wheel. The truck's innovative six-position Multipro tailgate and CarbonPro cargo bed added practicality, while the available mud-terrain tires emphasized its off-road capabilities. However, the Sierra's interior storage was less impressive compared to competitors, and its overall design felt dated.

The 2020 RAM 1500 offered a range of engine options, starting with a reworked 3.6-litre V6 engine paired with a ZF eight-speed automatic transmission, delivering 305 horsepower and 269 pound-feet of torque. The V6 featured a mild-hybrid system called "eTorque," which provided an additional 90 lb-ft of torque during towing and improved fuel efficiency. The optional 5.7-litre Hemi V8 engine offered 395 hp and 410 lb-ft of torque, with a maximum towing capacity of 5,783 kilograms (12,750 pounds) in 2WD configuration. The 3.0-litre EcoDiesel V6, with 260 hp and a class-leading 480 lb-ft of torque, was another option, although it experienced some turbo lag. The RAM 1500's fuel consumption varied depending on the engine and drivetrain, with the V6 achieving 12.2 L/100 km in the city and 9.7 on the highway with 4WD.

The 2021 GMC Sierra 1500 featured an affordable Duramax 3.0-litre turbodiesel six-cylinder engine, producing 277 horsepower and 460 pound-feet of torque. This engine was paired with a 10-speed automatic transmission, providing smooth gear changes and efficient power delivery. The Sierra's automatic four-wheel-drive system allowed for easy switching between RWD and 4WD modes. During testing, the Sierra averaged 11.1 litres per 100 kilometres, slightly higher than the official rating of 9.1 L/100 km. The AT4's suspension handled various terrains with ease, offering a comfortable ride both on and off-road. The Sierra's towing capacity with the Duramax diesel was up to 4,173 kilograms (9,200 pounds), making it a capable choice for towing and hauling.

6/10

The 2020 RAM 1500 excelled in interior space and comfort, offering a spacious cabin with class-leading torque and towing capacity. Its interior featured over 151 litres of storage, including a giant centre console and hidden pockets. The rear seats in higher trims could recline, providing ample legroom even for taller passengers. However, achieving the maximum towing capacity required specific configurations, limiting some functionality. The RAM 1500's dials were noted for being loosely calibrated, which could be frustrating for users.

The 2021 GMC Sierra 1500 provided comfortable seating with power adjustments and heated and cooled cushions. The rear seats offered heated outboard positions and rear air conditioning vents. The Sierra's innovative six-position Multipro tailgate and CarbonPro cargo bed added practicality, while the high-clearance side rails and rear bumper steps made access easier. The Sierra's bed held between 1,781 and 2,523 litres of cargo, depending on length, and featured up to 12 cargo tie-downs. However, the Sierra's interior storage was less impressive compared to competitors, with smaller and less innovative options.

The 2020 RAM 1500 stood out with its tablet-style 12-inch touchscreen and Uconnect system, offering a user-friendly interface and easy smartphone pairing. The RAM 1500's engine technology, including the diesel and eTorque mild hybrid system, was noteworthy for its industry-leading improvements. The truck featured push-button start and a wealth of USB and USB-C inputs, ensuring ample charging options for passengers.

The 2021 GMC Sierra 1500 offered numerous camera-based technologies, including a surround-view camera, trailer- and bed-view cameras, and a rear camera mirror. The optional Technology Package included a 15-inch head-up display and an 8-inch driver information display. The Sierra's infotainment system featured a choice between a 7-inch and an 8-inch touchscreen, with fast loading and responsive input. The test truck had the 8-inch display, which included physical menu shortcut buttons and excellent voice recognition technology. Wireless Apple CarPlay and Android Auto, along with a 4G LTE WiFi hotspot, were standard, while the available Bose premium sound system was adequate but not exceptional.

Safety

4/10

The 2020 RAM 1500 received a 5-star overall safety rating from the NHTSA and was the first full-size pickup truck to be named a Top Safety Pick Plus by the IIHS, provided it was equipped with the Crew Cab model and all active safety equipment. While most safety features were available across trims, none came standard, allowing buyers to choose only what they needed. The RAM 1500's hood design improved visibility, and its braking performance was consistent, though stopping distances were average for the class.

The 2021 GMC Sierra 1500 offered optional safety features like forward collision warning, front pedestrian braking, and automatic emergency braking. The Denali trim included blind-spot warning and rear cross-traffic warning, while adaptive cruise control was available on higher trims. The Sierra's crash-test ratings were less impressive, with a four-star overall rating from the NHTSA and "Marginal" ratings from the IIHS for certain tests. The Sierra's LATCH anchors also received a "Marginal" rating for accessibility.
