A car’s window sticker can tell you what a vehicle is supposed to cost, but it does not always tell you what buyers are actually paying. Automakers and dealers sometimes use cash incentives, loyalty offers, financing deals, and inventory-clearance programs to bring prices well below MSRP. That creates some eye-opening opportunities for shoppers who know where to look.
In September 2026, several luxury cars, electric vehicles, and full-size trucks stand out for having unusually large discounts. Some offers can cut five figures from the sticker price, although eligibility rules and dealer pricing can affect the final deal. Here are 10 vehicles currently showing some of the largest documented gaps between MSRP and available purchase incentives.

1. 2026 Mercedes-Maybach S 680
Potential discount: Up to $70,000
Nothing else on this list comes close to matching the sheer dollar figure attached to the Mercedes-Maybach S 680 right now. Mercedes bumped its incentive up to $70,000, a jump from the $35,000 offer that was already available just a month earlier.
That’s not a typo, and it’s not a small print gimmick either; it’s a genuine manufacturer-backed price cut that reflects just how eager the brand is to clear remaining inventory.
The reasoning behind such an aggressive number becomes clear once you consider timing. The 2027 S-Class is already arriving at dealerships, which puts pressure on remaining 2026 Maybach units sitting on lots collecting dust rather than generating revenue.
Rather than let these ultra-luxury sedans linger indefinitely, Mercedes decided to move them quickly through an incentive large enough to grab serious attention from wealthy buyers who might otherwise wait for the newer model.
It’s worth pointing out that the S 680 isn’t traveling alone here. Its sibling, the S 580 Maybach, is also carrying a substantial $45,000 incentive of its own, though it falls short of the S 680’s record-setting discount.
Together, these two models represent some of the most dramatic price reductions currently available anywhere in the new car market.
For buyers who’ve had their eye on ultra-luxury Mercedes ownership but balked at the original sticker price, this particular window through September 30 represents a genuinely rare opportunity to close that gap in a meaningful way.

2. 2026 Polestar 4
Potential discount: Up to $26,000
Electric vehicles have faced a bumpy road toward mainstream adoption, and the Polestar 4’s current incentive structure reflects just how aggressively certain EV makers are competing for buyer attention.
Cash purchasers can currently access a $25,000 incentive straight from Polestar, and returning customers eligible for the additional $1,000 loyalty discount can push that total savings all the way to $26,000 off the original sticker price.
That’s a genuinely massive percentage reduction relative to the vehicle’s starting price, transforming the Polestar 4 from a premium EV purchase into something considerably more accessible for shoppers who’ve been sitting on the fence about going electric.
Buyers considering financing options rather than paying cash outright will find a slightly different structure available to them. Choosing Polestar’s 0% financing program instead delivers an $18,000 incentive, still substantial, though noticeably smaller than the cash-purchase discount.
That same potential $1,000 loyalty bonus can still apply on top of the financing incentive for eligible returning customers, softening the gap between the two purchase paths somewhat.
This kind of two-tiered incentive structure, offering different savings depending on whether you pay cash or finance, has become increasingly common across the EV segment as manufacturers try to balance moving inventory quickly against maintaining healthy margins on financed deals.
Shoppers should run the numbers carefully on both paths before deciding which route delivers the better real-world value for their specific financial situation heading into a purchase decision before the September 30 deadline.

3. 2026 RAM 1500
Potential discount: Up to $13,739
Truck buyers also have a good opportunity to save on the 2026 RAM 1500 this month. RAM is offering 12% off MSRP on several configurations, while selected Rebel, Limited, and Tungsten Crew Cab models qualify for up to 15% off the sticker price.
For the top-end Tungsten trim, the 15% discount can amount to as much as $13,739. That is a substantial saving, especially for buyers who want a well-equipped truck without paying the full sticker price. It could make the higher trim more affordable without having to move down to a less expensive version.
There is, however, an important condition buyers should understand. This particular discount cannot be combined with other offers, so you may not be able to add another cash rebate or special financing deal to it. The RAM 1500 RHO is also excluded from this promotion.
The offer is available through September 30, 2026, but buyers should confirm the exact terms before making a purchase. The discount can vary depending on the trim, vehicle configuration, dealer, and customer eligibility.
If you are considering a RAM 1500, it is worth asking the dealer for the final selling price after the applicable discount. Comparing that figure with other available financing or cash offers can help you choose the deal that gives you the best value.

4. 2026 INFINITI QX80
Potential discount: $10,000
Luxury SUV shoppers have a genuine opportunity sitting in front of them with the current INFINITI QX80 incentive. Every trim level currently qualifies for $10,000 in Retail Bonus Cash, a straightforward discount that applies broadly rather than being restricted to just the entry-level or fully loaded configurations.
Timing plays a considerable role in why this incentive exists at such a substantial level right now. The 2027 QX80 has already started arriving at dealerships, creating the same kind of inventory pressure that’s driving discounts across several other models on this list.
Dealers holding remaining 2026 units have clear motivation to move that inventory before showroom floor space becomes increasingly valuable for the newer model year arriving alongside it.
INFINITI itself has confirmed this $10,000 offer applies to eligible 2026 QX80 purchases, lending official backing to what might otherwise sound like an unusually generous discount for a full-size luxury SUV.
That said, buyers should understand that eligibility requirements and specific financing combinations can vary depending on individual circumstances, credit qualifications, and regional dealer participation, so confirming exact terms locally before finalizing a purchase decision remains a smart step.
For families or buyers specifically drawn to the QX80’s blend of luxury, space, and capability, this incentive window offers a genuine chance to secure a nearly new-generation SUV at a meaningfully reduced cost compared to what the vehicle commanded when it first launched, all before the September 30 deadline closes this particular opportunity.

5. 2026 Genesis G90
Potential discount: Up to $10,000
Genesis has been steadily building its reputation as a genuine luxury contender, and the current G90 incentive structure shows the brand isn’t afraid to compete aggressively on price when circumstances call for it.
Current data shows $10,000 in available savings, delivered through a combination of Retail Bonus Cash paired with a Loyalty or Competitive Owner Bonus depending on individual buyer eligibility.
Breaking that number down against the G90’s typical pricing reveals just how substantial this discount actually is. With an MSRP sitting around $94,245, that $10,000 reduction works out to approximately 11% off the original sticker price, calculated before any additional negotiation a buyer might pursue directly with their local dealership.
For a flagship luxury sedan competing against considerably more established German and Japanese rivals, that kind of percentage reduction represents genuine value for shoppers willing to consider a newer luxury brand still building broader market recognition.
The Competitive Owner Bonus portion of this incentive specifically rewards buyers currently driving vehicles from rival luxury brands who are considering switching to Genesis, a common industry tactic designed to poach loyal customers away from competing manufacturers during a purchase decision window.
Combined with the standard Retail Bonus Cash available to all qualifying buyers, this creates a genuinely attractive entry point into flagship luxury sedan ownership.
Buyers interested in the G90 should move relatively quickly, since this particular incentive window closes September 8, considerably earlier than several other offers on this list that extend through the end of the month.

6. 2026 Kia Niro EV
Potential discount: $10,000
Compact electric vehicles have struggled to compete with gas-powered alternatives on price, but the current Kia Niro EV incentive is working hard to close that gap.
A $10,000 Customer Cash incentive currently applies to purchases, representing one of the more accessible EV discounts currently available across the broader market. Applied specifically to the entry-level Wind trim, this discount creates genuinely compelling pricing.
Estimates suggest the rebate effectively brings that base configuration down to roughly $31,000, a price point that starts competing directly with plenty of gas-powered compact SUVs rather than sitting in typical EV price territory that’s scared away budget-conscious shoppers in the past.
That accessibility matters considerably for buyers who’ve been curious about electric vehicle ownership but felt priced out by the premium many EVs still command compared to traditional gas alternatives.
Bringing an EV’s effective price down into more mainstream territory removes one of the biggest psychological barriers preventing wider adoption among everyday car shoppers who aren’t necessarily early adopters chasing the latest technology regardless of cost.
Kia has positioned the Niro EV as a practical, everyday-usable electric option rather than a flashy performance statement, and this pricing incentive reinforces that positioning nicely.
For shoppers specifically hunting for the most affordable path into EV ownership currently available, the Niro EV’s combination of reasonable base pricing and this substantial $10,000 rebate makes a genuinely strong case worth serious consideration before the September 30 offer period closes.

7. 2026 Kia EV9
Potential discount: Up to $10,000
Families needing three rows of seating in an electric package have a genuine opportunity with the current Kia EV9 incentive. Up to $10,000 in Customer Cash is currently available on this larger electric SUV, bringing meaningful savings to a segment where three-row EV options remain considerably more limited compared to traditional gas-powered alternatives.
That discount can make a real difference in total purchase price, particularly for buyers who need the extra seating capacity and cargo space the EV9 provides but were hesitant about the higher starting price typically associated with larger electric vehicles.
Three-row EVs generally carry premium pricing compared to their two-row counterparts, given the additional battery capacity and structural requirements needed to support the larger footprint, making this incentive particularly valuable within its specific vehicle category.
There’s an important decision point buyers need to consider before finalizing their purchase approach, though. Kia’s current promotional structure generally requires choosing between this cash rebate and the manufacturer’s promotional financing offers rather than combining both simultaneously.
That means shoppers need to run the actual numbers on their specific situation, comparing what the $10,000 cash discount saves against what promotional financing rates might save over the life of a loan, before determining which path delivers better real-world value for their particular circumstances.
For growing families specifically drawn to electric vehicle ownership but needing the practicality of three rows, the EV9’s current incentive structure through September 30 offers a genuine opportunity to make that transition more financially comfortable than sticker price alone would suggest.

8. 2026 Hyundai IONIQ 9
Potential discount: Up to $10,000
The Hyundai IONIQ 9 is currently one of the electric vehicles offering a good discount. Buyers can get up to $10,000 off the MSRP, and on the entry-level SE trim, that amounts to more than 15% off the original sticker price.
A discount of more than 15% is quite attractive, especially for a three-row electric SUV. With this offer, the IONIQ 9 becomes more affordable for buyers who may have been considering other electric SUVs in the same category.
Hyundai also has a separate financing offer that provides 0% interest together with bonus cash for qualified buyers. However, these offers generally cannot be combined.
Buyers should therefore compare both options carefully before making a decision. Depending on your credit, down payment, and preferred loan period, the financing offer could sometimes save you more than taking the larger cash discount.
The current $10,000 offer is available through September 8, 2026. Anyone interested in the IONIQ 9 should confirm the offer with a dealer before buying, as incentives can change and may depend on eligibility and vehicle availability.

9. 2026 Honda Prologue
Potential discount: Up to $9,250
Honda’s relatively new entry into the electric SUV segment is currently carrying substantial incentives, driven partly by news that the Prologue’s production run is scheduled to end after this exact model year.
That upcoming discontinuation creates genuine urgency for dealers holding remaining inventory, and the resulting discount structure reflects that pressure clearly. Buyers can currently access up to $9,250 off MSRP through a layered combination of incentives rather than one single rebate source.
Honda Financial Services is offering $7,250 in lease cash, while an additional $2,000 in Conquest Cash becomes available specifically for shoppers currently driving vehicles from certain competing brands who are considering switching over to Honda for their next purchase.
This combination approach means the maximum discount isn’t universally available to every single shopper walking through the door.
Buyers need to specifically qualify for the Conquest Cash portion by owning an eligible competing brand vehicle, meaning current Honda owners or those coming from non-qualifying brands might only access the base lease cash portion rather than the full combined incentive amount.
Given that Honda has confirmed this model’s production will conclude after the current model year, remaining Prologue inventory represents something of a closing chapter for the nameplate.
Buyers interested in securing one of these vehicles at meaningfully reduced pricing should act before the September 8 deadline, particularly if they can qualify for the additional conquest incentive that pushes total savings toward that $9,250 maximum figure.

10. 2026 GMC Sierra 1500
Potential incentive: Up to $7,750
The GMC Sierra 1500 remains a good option for truck buyers looking for a reasonable discount. However, there has been some confusion about the discount available on specific trims.
Claims that the AT4X is currently receiving an average discount of $8,000 are not supported by verified figures, so buyers should work with confirmed offers when negotiating. At the moment, eligible Sierra 1500 models can attract up to $7,750 in cash incentives.
Some financing offers also provide up to $6,000 in cash incentives together with 0% APR for qualified buyers. This may be a better option for someone who wants to reduce financing costs rather than focus only on the largest cash discount.
There are also attractive lease offers on selected Sierra models. For buyers who prefer lower monthly payments and do not plan to keep the vehicle for many years, leasing may provide better short-term value.
However, the final amount you can save depends on the trim, financing option, eligibility, and dealer participation. If you are planning to buy one, ask the dealer for a written breakdown showing the vehicle price, incentives, fees, financing terms, and final amount payable. This will help you know exactly what you are getting before committing.
