Volvo built a record-smashing 2,400 HP truck as fast as a Porsche 911

By Ronan Glon Published August 25, 2016

Semi trucks and speed records are generally considered mutually exclusive, but Volvo Trucks has developed and built a one-off big rig that recently broke two Guinness World Records on a closed-off airfield in Sweden.

Volvo’s experimental truck is dubbed the Iron Knight, a name that’s slightly misleading because its cab is made entirely out of carbon fiber in order to shed as much weight as possible. The truck features a unique design that looks more futuristic than any comparable big rig on the market today, as well as a stripped-out interior with a roll cage and a Recaro bucket seat.

The Iron Knight is based on a regular-production FH truck. Engineers have made significant modifications to the midmounted, 12.8-liter turbo diesel engine in order to bump its output up to 2,400 horsepower and a jaw-dropping 4,425 pound-feet of torque. The list of modifications includes installing four turbochargers, and adding a water-cooled intercooler. Surprisingly, the oil-burner’s astonishing amount of power is channeled to the drive wheels via a stock dual-clutch automatic transmission.

As a result of the upgrades, this 9,000-pound beast is capable of hitting 60 mph from a stop in 4.6 seconds, about on par with a base Porsche 911. It covered 500 meters (about 546 yards) in 13.7 seconds at an average speed of 81 mph, and a kilometer (roughly 1,100 yards) in 21.2 seconds at an average speed of 105 mph. Both of those are all-time records for a big rig. And if that’s not impressive enough, it maxed out at 171 mph during one of the two runs.

While setting land speed records in a big, heavy semi truck sounds like little more than a PR stunt, Volvo explains it’s going through the trouble for the sake of research and development. The technology features designed to make the Iron Knight as fast as a sports car will trickle down to series-produced trucks in the coming years.

“Our aim was to generate new insights into technical and design solutions. The intention is to transfer some of these to our series-produced trucks,” Claes Nilsson, the CEO of Volvo Trucks, explained in a statement.

Plug-in hybrids are becoming more popular. Why? And will it continue?

There's a lot of talk about the idea that the growth in electric car sales has kind of slowed a little. It's not all that surprising -- EVs are still expensive, early adopters all have one by now, and they're still new enough to where there aren't too many ultra-affordable used EVs available. But plenty of people still want a greener vehicle, and that has given rise to an explosion in hybrid vehicle sales.

That's especially true of plug-in hybrid vehicles, which can be charged like an EV and driven in all-electric mode for short distances, and have a gas engine as a backup for longer distances or to be used in combination with electric mode for more efficient driving.

EV drivers are not going back to gas cars, global survey says

Nearly all current owners of electric vehicles (EVs) are either satisfied or very satisfied with the experience, and 92% of them plan to buy another EV, according to a survey by the Global EV Drivers Alliance.

The survey of 23,000 EV drivers worldwide found that only 1% would return to a petrol or diesel car, while 4% would opt for a plug-in hybrid (PHEV) if they had to replace their car.

Trump team in sync with Tesla on ending crash-reporting requirements, report says

The transition team of President-elect Donald Trump is planning to end existing car-crash reporting requirements to safety regulators, according to a Reuters report.

The report cites a document obtained by Reuters that lays out the transition team’s 100-day strategy for automotive policy. In the document, the team says the crash-reporting requirement leads to “excessive” data collection, Reuters says.
