Costco Executive members may be eligible for up to $2,000 toward the purchase or lease of a 2026 or 2027 Ineos Grenadier, including the Station Wagon and Quartermaster pickup variants. The offer applies only to vehicles delivered between October 1, 2026, and January 4, 2027.

The promotion comes as Ineos pursues US sales growth of as much as 35 percent year over year. Costco’s Auto Program commonly extends offers to both Gold Star and Executive members, but this Grenadier incentive is limited to Executive members.

Grenadier eligibility and accessory credit

Eligible members can receive a $2,000 vehicle incentive when they buy or lease a qualifying Grenadier. With Grenadier pricing starting above $70,000, the discount represents a relatively small reduction in the vehicle’s cost, although it can be combined with other Ineos incentives.

Executive members will also receive a $1,000 credit toward Ineos accessories. To qualify, the Costco membership must have been active before September 30. People who joined on or after that date are not eligible for the offer.

Ineos discounts can be combined

In addition to the Costco incentive, Ineos is offering several customer cash discounts on Grenadier models. The basic versions currently carry a $1,000 offer, while the 2026 Fieldmaster is eligible for $2,000 in customer cash.

The Grenadier Trailmaster has a $3,000 customer cash offer, and the Trailmaster X is available with $2,000 in customer cash. Combining the Costco promotion with the standard Trailmaster’s $3,000 offer could produce total savings of $5,000, not $6,000, before considering the separate accessory credit.

Other Costco Auto Program offers

Costco is also offering incentives on several other vehicles. Gold Star members can save $1,000, while Executive members can save $1,250, on a new Volkswagen Atlas, Atlas Cross Sport, Tiguan, or Taos.

The electric Volvo EX90 carries a $2,000 discount for Executive members and a $1,500 discount for Gold Star members. Costco members can also receive discounts ranging from $1,000 to $1,250 on the Volvo EX40 and EX30.
