In a world where cars are getting bigger and heavier, it's fascinating to explore the extremes of automotive design. From the luxurious to the utilitarian, these seven vehicles showcase the diverse ways in which car manufacturers are pushing the boundaries of size and functionality. Each of these cars is longer than a Sherman tank, a testament to the evolution of automotive engineering and the changing needs of drivers. Let's delve into the details of these remarkable vehicles and the stories they tell.
The Ultimate in Opulence: Rolls-Royce Phantom Extended
The Rolls-Royce Phantom Extended is a masterpiece of automotive engineering and a symbol of opulence. At 236 inches long, it stretches farther than certain versions of the M4 Sherman tanks, yet it remains narrower and lower than those military behemoths. This car offers all the best bits of luxury driving, along with massive customization opportunities to create a highly individual vehicle. Under its hood, a mighty V12 powerplant generates 544 horsepower and 738 pound-feet of torque, allowing the car to go from 0 to 62 mph in 5.5 seconds. Top speed is also impressive, at 155 mph. While these specifications may have little real-world relevance to most drivers, they highlight the engineering prowess behind this vehicle. The latest Rolls-Royce Phantom VIII EWB versions are priced new from around $637,750, but used Phantom VII EWB examples are more attainable at around $120,000 to $154,300.
The Ultimate in Bespoke Luxury: Maybach 62
The Maybach 62 is another bespoke model to consider if you want a really large car. Named for its nearly 6.2 meters of length, it is 78 inches wide and 62 inches tall. This car's sheer size puts it firmly ahead of most Shermans, including the early production M4A4 and late production M4A6 variants. Despite its size, the Maybach 62 is quite substantial when compared to the regular-size fifth-generation Mercedes-Benz S Class. Used Maybach 62 models are priced from around $45,000 to over $100,000, while the Maybach 62S variant, built for chauffeur driving, starts from $75,000.
The Ultimate in Limousine Luxury: Mercedes-Maybach S600 Pullman
The Mercedes-Maybach S600 Pullman is a favorite of the ruling class and one of the figureheads among modern limousines. At 255.6 inches long, it is 7+ inches longer than the biggest M4 Sherman tanks and almost 40 inches longer than the already lengthy 2027 Mercedes-Maybach S-Class. The chauffeur-driven limo arrived back in 2015, filling in the void left by Pullmans of old. Pricing kicked off from a sky-high $566,922, but this was obviously not a problem for the well-heeled buyers they were intended for, seeing as the S600 Pullman sold out immediately for two years. In 2018, the manufacturer offered an updated Maybach S650 Pullman as part of a mid-life facelift for the S-Class lineup, keeping the S650 Pullman's dimensions identical to the S600.
The Ultimate in Workhorse Capability: Ram Heavy Duty
The Ram Heavy Duty is one of the longest pickup trucks you can buy new, at nearly 261 inches long. The longest Ram HD trucks are the crew cab models with an 8-foot-long bed, which come in at an impressive 260.8 inches. The Ram HD trucks keep the Hemi alive with a 6.4-liter Hemi V8 that generates 405 horsepower and 429 pound-feet of torque, sent to the wheels via an eight-speed automatic transmission. Ram also offers a 6.7-liter turbodiesel inline-six with 430 hp and 1,075 pound-feet of torque. The 2026 Ram 2500 HD is priced from $46,855, while the 3500 HD starts at $48,155.
The Ultimate in Towing Capability: Ford F-Series Super Duty
The Ford F-Series Super Duty is the hardest-working of them all, with a max towing capacity of 40,000 pounds, the highest towing capacity of any pickup truck ever made. That's in addition to its vast length of up to 266.2 inches, which gives occupants a spacious interior and generous cargo space, with a maximum payload rating of 8,000 pounds. The 2026 Ford F-Series Super Duty can be had from $45,975.
The Ultimate in Workhorse Capability: Chevrolet Silverado HD and GMC Sierra HD
The current-generation Chevrolet Silverado HD is one of the cheapest options in its class, with prices starting from $45,900. That nets you a competent workhorse capable of pulling up to 36,000 pounds with the diesel engine. The Silverado HD can be had with either a standard 6.6-liter gas V8 producing 401 horsepower and 464 pound-feet of torque or an available Duramax 6.6-liter turbocharged diesel that's good for a thumping 470 hp and 975 pound-feet. The 2026 GMC Sierra HD starts at $47,000.
The Ultimate in Limousine Luxury: 1974 to 1976 Cadillac Fleetwood Seventy-Five
Nobody does land yachts like Cadillac, and the Fleetwood 75 is a throwback to the golden age of its behemoths. Produced across 11 generations from 1936 until 1987, the long-wheelbase Cadillac Series 75 was known for being quite imposing. The largest of them all was only sold in the 1974 to 1976 model years, with a length of 252.2 inches. Despite their massive sizes, these seemingly unwieldy limousines can even rally if you're prepared to put the time into mastering them. The '75-to-'76 Fleetwood 75s came with a naturally aspirated 500-cubic-inch (8.2-liter) V8 engine producing 190 horsepower, with torque at 360 pound-feet. The 1974 model had a 472-cubic-inch (7.7-liter) V8 producing 205 horsepower. Finding one today will require parting with a significant sum, as evidenced by a 1972 Cadillac Fleetwood Series 75 Limousine, which sold for around $53,000.
