Navistar has lost US Class 8 market share since the introduction of its 2010 models in August last year.
Between August 2010, when the manufacturer had worked through its 2009 model overhang, and April 2011 Navistar's Class 8 market share fell by 6.1%, from 26.5% to 20.4%, compared to the same period in the previous year, according to discoverDEF.com's analysis of Ward's Auto data.
In the nine months since the introduction of its new 2010 models Navistar sold 18,857 units compared to 20,240 in the same period in the previous year. During the same time frame overall domestic Class 8 sales increased by 17.5%.
Navistar is the only manufacturer not to use Selective Catalytic Reduction (SCR) technology to meet the Environmental Protection Agency's 2010 emissions standards for heavy-duty trucks, relying instead on an advanced Exhaust Gas Recirculation (EGR) system and emissions credits earned in previous model years.
Responding to the figures a Navistar spokesperson told discoverDEF.com: "As our senior executives have been saying for some time, we had a slow ramp up with our new advanced EGR engine strategy.
"We are now on track to deliver on our commitments in the second half of fiscal 2011 and we continue to see growing customer acceptance of our 13 liter advanced EGR MaxxForce and our new 15 liter advanced EGR engines. Market share gains will come in the months ahead."
According to Navistar's latest available results, in the quarter ending 31 July 2010 it had 30% of the Class 8 market share, in the quarter to 31 October 2010 this dropped to 20% and in the three months to 31 January 2011 to 17%.
PACCAR was the only other North American manufacturer to lose ground during the nine-month period, with its market share dropping by 0.3% to 24.73% year on year. Volvo made the biggest gain, increasing its market share by 3.9% and sales from 12,126 to 18,357 vehicles year on year between August 2010 and April 2011.
PACCAR, Volvo and Daimler had all begun delivering 2010 models by August 2010.
