Ineos has an ambitious plan to grow its US sales by up to 35 percent year over year, but it might need a little help to make this happen. This could explain why it’s partnered with Costco to give members an exclusive discount. However, not everyone is eligible.
Ordinarily, Costco’s Auto Program provides discounts to both Gold Star and Executive members, but in this case, it’s only Executive members who can get a discount on a 2026 or 2027 Ineos Grenadier. The $2,000 incentive isn’t hugely significant given that Grenadier prices start at over $70,000, but it might be enough to convince some tempting buyers to take the plunge.

Shoppers will receive the incentive if they purchase or lease either a 2026 or 2027 Grenadier, including either the standard Station Wagon or the Quartermaster pickup version. The key condition is that the vehicle must be delivered between October 1, 2026, and January 4, 2027.
Costco Executive Members will also receive a $1,000 credit to put towards any of Ineos’s accessories. If you weren’t a Costco member before September 30, you’re not eligible for this deal.
Ineos Has Its Own Incentives

The Costco incentive can be combined with any other discount Ineos is offering. Currently, the British company has a $1,000 customer cash offer for all basic Grenadier models, a $2,000 customer cash offer for the 2026 Grenadier Fieldmaster, a $3,000 cash offer for the Grenadier Trailmaster, and a $2,000 offer for the Trailmaster X. Combine the $3,000 cash offer for the standard Trailmaster with the Costco deal and you’re looking at $6,000 in savings.
Other Costco Deals
The Costco Auto Program also has deals on several other cars right now. Gold Star and Executive members can currently save $1,000 and $1,250, respectively, when purchasing or leasing a new Volkswagen Atlas, Atlas Cross Sport, Tiguan, or Taos. In addition, the all-electric Volvo EX90 is available with a $2,000 discount for Executive members and $1,500 off for Gold Star members. Costco is also offering discounts of $1,000 to $1,250 on the Volvo EX40 and Volvo EX30.
