Sure, here are three rival vehicles that can stand toe-to-toe with the 2015 Volvo VNL Tractor:
2016 Freightliner Cascadia: This truck is a competitive option when considering its efficiency and reliability. It features a Detroit DD13 engine, which offers similar horsepower to the Volvo's D13 engine. The Cascadia also comes with an automated manual transmission, providing a comparable driving experience to the I-Shift system found in the Volvo VNL.
2015 Peterbilt 579: Known for its durability and strong performance, this model could be an alternative to the Volvo VNL. It's powered by a PACCAR MX-13 engine delivering up to 430HP, slightly more than the Volvo's D13 engine. The 579 also includes an Eaton Fuller automated transmission, mirroring the ease of use provided by Volvo's I-Shift.
2016 Kenworth T680: This vehicle is renowned for its fuel efficiency and driver comfort - two aspects that are crucial for long-haul drivers. Its PACCAR MX-13 engine offers similar power outputs as seen in the Volvo VNL's D13. Additionally, it includes an Eaton Fuller UltraShift Plus transmission system for smooth gear shifts, making it a worthy adversary to the I-Shift equipped in the Volvo.
