Isuzu may be out of the car and consumer truck/SUV business in the U.S., but it's still a major player in the commercial truck market, with its N-series medium-duty cabover trucks being the best-selling models in the segment. Highlighting the changes for the 2014 and 2015 trucks are larger allowable frontal areas facilitating larger bodies, a new radio head unit, and a new air conditioning compressor on the NPR Eco-Max model.

The frontal area on the 2014 Isuzu NPR Eco-Max has been increased from 6.92 square meters to 7.4, allowing models lacking air deflectors to accommodate bodies with inside heights up to 85 inches without application approval from Isuzu. Air-deflector-equipped models can accommodate bodies with inside heights up to 91 inches with application approval.

The Eco-Max model with the 151-inch wheelbase also gets a dual fuel tank option with a 33-gallon side-mounted fuel tank. The Eco-Max, as well as the heavier-duty NPR-HD, NQR, and NRR models get a new radio headunit with a CD player and USB input. HD models also get new 19.5-inch Bridgestone low rolling-resistance tires for improved fuel efficiency. The 2015 NPR Eco-Max model with the 3.0-liter I-4 engine will get the same Denso air conditioning compressor used on 5.2-liter models.

Isuzu is also continuing its 24-month/60,000-mile maintenance program for all 2014 and 2015 N-series diesel trucks.
