Sure, here are three rival vehicles to the 2015 Volvo VNL Tractor Truck:
2015 Freightliner Cascadia
This truck is a worthy competitor to the Volvo VNL with similar capabilities. It features a Detroit DD15 engine and an automated manual transmission that provides smooth shifting for optimal fuel efficiency. It has around 500,000 miles on it, so it's comparable in terms of usage. The Freightliner Cascadia also has a sleeper cab feature for long hauls.
2016 Kenworth T680
The Kenworth T680 is another excellent alternative. It comes equipped with a PACCAR MX-13 engine and an Eaton Fuller automated transmission, offering similar power and performance to the Volvo D-13 engine and I-shift transmission. With its tandem axle setup and sleeper cab, it shares many similarities with the 2015 Volvo VNL.
2014 Peterbilt 579
Despite being a year older, this truck can still compete with the best of them. Its Cummins ISX15 engine offers comparable horsepower to the Volvo D-13 engine in the VNL model. Like the Volvo, this Peterbilt model also features an automatic transmission for easy handling and a sleeper cab for convenience on long trips.
