Navistar says it's the first truck and bus manufacturer to receive total hybrid vehicle certification from the California Air Resources Board for improving fuel economy and overall emissions.

Customers who purchase certified International and IC Bus vehicles receive additional $5,000 voucher under the state program. The International DuraStar Hybrid box van, utility truck and IC Bus CE Series hybrid bus are CARB-certified.

Last week, CARB voted to implement a $25 million voucher incentive program as part of California Assembly Bill (AB) 118 to accelerate the deployment of about 1,000 medium- and heavy-duty diesel hybrid trucks and buses in California. Purchasers of commercial hybrid vehicles under this program will receive incentives ranging from $10,000 to $35,000 per vehicle depending on weight class. In addition, purchasers of CARB-certified International DuraStar Hybrid models and IC Bus hybrid buses will receive vouchers worth another $5,000 per vehicle under the incentive.

"This is a win-win for everyone in California," said Jack Allen, Navistar president, North American truck group. "By working together we created the opportunity to put more clean diesel hybrid trucks and buses on California's roads, and we're proud that Navistar's hybrid leadership directly puts money back in our customers' pockets."

AB 118, authored and championed by former California State Assembly Speaker Fabian Nunez, aims to reduce greenhouse gases from California's transportation sector, and was signed by Governor Schwarzenegger on Oct. 14, 2007.
