Here’s the technology that helped create the world’s fastest tractor

JCB Fastrac does 103.6mph and sets new British record

It’s amazing what technology can do. Farm tractors spend most of their plodding along at walking pace, but this one can go over 100 mph.

The JCB Fastrac 8000 just broke the record for world’s fastest tractor, with a top speed of 103.6 mph. The record was broken at a British airfield, with television personality and motorcycle racer Guy Martin at the wheel. Martin smashed the previous record of 87.27 mph, which was set in 2018 on Top Gear, using “tame racing driver” The Stig.

JCB, a large British manufacturer of tractors and construction equipment, needed some help to get more speed out of its machine. So it turned to Williams Advanced Engineering, the engineering arm of the Williams Formula One team, which JCB sponsors. Williams currently makes the slowest cars on the F1 grid but, having worked on things like the scrapped Jaguar C-X75 supercar, it was more than up to the task of helping to design the world’s fastest tractor.

Williams made some aerodynamic changes to the otherwise barn-like tractor, and helped remove weight. Some of the weight-saving measures included fitting the Fastrac 8000 with a tiny fuel tank, and using the chassis from a lighter-duty 4000-series Fastrac model, according to Farmers Weekly.

The tractor is powered by a 7.2-liter six-cylinder diesel engine making 1,000 horsepower and 1,843 pound-feet of torque. Two turbochargers and an electric supercharger allow the engine to make that prodigious level of power. Farmers Weekly also reports that the stock continuously variable transmission (CVT) was swapped for a ZF six-speed manual from a semi truck. The stock four-wheel drive system was also ditched. All power is sent to the rear wheels through an axle with no differential.

Automotive speed records can sometimes kick off arms races among competing manufacturers, but it’s unclear if, say, John Deere or New Holland will pick up the gauntlet thrown down by JCB. But the Fastrac 8000 isn’t the only improbably fast vehicle to set a record recently.

According to Guinness World Records, the Honda Mean Mower is now the quickest lawn mower from zero to 100 mph, with a time of 6.285 seconds. It’s also likely the only lawn mower that can reach 100 mph, period. The Mean Mower is powered by a 190-hp engine from a Honda CBR1000RR motorcycle.

Mercedes-Benz G580 first drive: old-school off-roader goes electric
2025 Mercedes-Benz G580 from three quarter view.

American car buyers mostly know Mercedes-Benz as a luxury brand. But for decades, the automaker has also produced the tough, rugged G-Class (also known as the Geländewagen or G-Wagen), an SUV not afraid to get its leather upholstery muddy. And now, this iconic Mercedes is going electric.

The 2025 Mercedes-Benz G580 with EQ Technology — the final name of the SUV previously known as the EQG — isn’t the first electric off-roader. The Rivian R1S and R1T and GMC Hummer EV have proven that electric powertrains and off-roading are a great combination. But the electric G-Wagen is different because it’s based on an internal-combustion model — and a very traditional one at that.

Honda believes hydrogen semi trucks will make the case for fuel cells
Honda hydrogen fuel-cell semi truck.

Honda remains committed to hydrogen fuel-cell vehicles, but the market for those vehicles remains limited. So Honda is looking at other uses for fuel cells -- including commercial trucks.

To show how that could work, Honda converted a semi truck to fuel-cell power, replacing its diesel engine with three fuel-cell modules. Together, the three modules produce a combined 321 horsepower, and can propel the truck to a top speed of 70 mph. There's enough onboard hydrogen storage capacity for a 400-mile range with a full load, Honda claims.

Mercedes-Benz G580 vs Rivian R2: Is the much cheaper Rivian actually better?
2025 Mercedes-Benz G580 from three quarter view.

Mercedes-Benz has finally taken the wraps off of the new "Mercedes-Benz G580 with EQ Technology." Yeah, it's a mouthful, but it's basically a new electric G-Wagon. It looks a lot like the G-Wagon you know and love, but with an electric powertrain and a battery. It's not the only electric SUV out there, however, and there are some great ones -- like the Rivian R2.

Both the Mercedes G580 and the Rivian R2 have a lot going for them, but they also approach the electric SUV slightly differently. Is one better than the other? I put the two head-to-head to find out.

The approach that the two vehicles take to design is quite different -- and you might like one better than the other.
