They don’t make them this way anymore! Tommy compares a Chevy Suburban / GMC Yukon XL HD 8.1L V8 to a Ford Excursion 6.8L V10. These two huge family movers have big displacement engines, three rows of seats, 4-wheel-drive, cavernous cargo holds, and big trailer towing capability. Tommy compares the two power plants with an impromptu 0-60 MPH acceleration test. Next up he takes them through Andre’s Pit series of off-road obstacles and our ranch.
The big-block 8.1-liter V8 in the GMC was rated at 320 horsepower and 440 lb-ft of torque when it was new. The large V10 in the Ford had a rating of 310 horsepower and 425 lb-ft of torque. These are high-torque gasoline engines that can pull tremendous weight. Naturally, these engines and transmissions get a bit tired after many years and many miles of use. The GMC Yukon XL takes the acceleration test, even with over 294,000 miles on its odometer.
The off-road capability of these two is much closer, but this Ford Excursion is not equipped with a limited-slip or a locking differential. The big GM SUV has a G80 automatically locking mechanical rear locker. This is what helps it tackle the “Trenches” obstacle and come out on top.
It’s great to see these large SUVs in the wild. Join the video below for all of the details.
