Some of Cummins’ newest engines are being delayed, CCJ (owned by Fusable, parent company of TPS) first reported Tuesday.
According to sources cited by CCJ, Cummins is delaying the launch of its X-10 and 7-liter B-Series engines. The X-10, which was teased earlier this year at the Work Truck Show, was intended to launch in January and will now debut in July.
The new B7.2 was supposed to launch in 2027 but now will not reach the market until 2028, CCJ reports.
CCJ states Cummins will fill the openings in its product lineup with existing engines — the L9 and X12 in the heavy truck space, and the B6.7 for medium-duty and vocational markets. Additionally, since all of these models are non-compliant under EPA 2027 regulations, CCJ reports Cummins will pay the fines associated with selling the engines and pass the cost through the engines’ prices.
The Cummins X15 diesel, itself also originally delayed about six months, is still on pace to make its market debut for model year 2027, CCJ reports.
Meeting regulatory requirements have been a challenge for all engine makers since the EPA announced its intent to amend the 2027 regulations late last year, and a final rule still has not been released.
Cummins told CCJ Tuesday it will review the rule when published. In the meantime, it states it will “continue to move forward with a product plan focused on dependable solutions that deliver meaningful benefits.”
