As far as modern-day, aero-focused semi-truck designs go, the Peterbilt 579 stands out as one of the best-looking ones. I much prefer the look of a traditional semi, like the 389, but if I had to choose something with a modern aesthetic, the 579 would be high on my list.
Peterbilt launched the Model 579 in 2012 as a wide-cab aerodynamic tractor – a direct replacement for the 587, even though the latter remained in production (it got replaced as the flagship truck). The 579 came with this sleek new cab design featuring improved outward visibility (gone were the vent windows), new body skirting, and an optimized under-body design.
Alright, technically both the 579 and the 389 stood tall as co-flagship models, sort of a “two sides of the same coin” type of deal. Alas, we’re not here to talk about the 389 (as tempting as that would be), because we just found this stunning, brand-new 2024 Peterbilt 579 with an Ultraloft Sleeper configuration, and the asking price is a whopping $199,500.
That’s basically what dealerships keep hoping people will pay right now for a low-mileage Challenger SRT Demon 170, but that’s not happening anymore. This Peterbilt is selling for $200k way faster than any Demon 170 might (but probably won’t).
Let’s unpack the specs, starting with the exterior which is finished in Hunter Green. Let me be on the record saying it looks absolutely stunning. It’s a dark green that almost looks black in the shade. Only under direct sunlight does the green hue shine through.
Other visual highlights include the Aero bumper, dual aluminum 120-gallon fuel tanks, a massive 80” double bunk UltraLoft sleeper with the Epiq aero package, plus air disc brakes on all axles to go with the 275/80R22.5 tires and an 18” air slide fifth wheel.
The so-called Premier interior features a leather-wrapped steering wheel, dual air ride leather seats, a 1,800W inverter with shore power, bunk heater, two beds (stacked one over the other), a refrigerator and a coffee maker. All that’s missing is a makeshift toilet, but otherwise you can easily live in this thing while using truck stop bathrooms.

As for what this semi can do in terms of performance, it’s got that Flex Air suspension for comfort, while a Cummins X15 turbocharged diesel engine provides pulling power. This particular X15 is rated at 450 horsepower and 1,650 lb-ft of torque, channeled to the wheels via a 12-speed Endurant automatic transmission.
Bottom line, if you need a capable semi tractor moonlighting as a decent enough camper, this Peterbilt 579 could make for a solid investment. However, if you need something that’s a lot more home-like, so to speak, feast your eyes on this custom 2023 Peterbilt 389 with a massive 168” (4.26 meter) sleeper section.
That one’s got a fully equipped kitchen, bedroom and bathroom, although it’s going to cost you no fewer than $409,900.
Sergiu got to experience both American and European car "scenes" at an early age (his father drove a Ford Fiesta XR2 supermini in the 80s). After spending over 15 years at local and international auto publications, he's starting to appreciate comfort behind the wheel more than raw power and acceleration. Full profile
