Retail advertised inventory data for January 2024: S&P Global Mobility delivers the following US new vehicle market insights:

Overall industry inventories

Available new vehicle dealer inventory listings for the US market continued to surge as of the end of December. A steady upward increase in advertised inventories has continued since August, and now stands at 2.45 million vehicles.

Of course, sales are also on the rise. But plotting year-over-year inventory growth, versus year-over-year sales growth, shows that relative to volume, inventories are up 30%.

As inventories grow, listed prices and average MSRPs are dropping - signaling automakers are building lower-trim models. But also the number of vehicles with advertised prices listed below MSRP are growing steadily. At the end of November, the average advertised discount was $2,742; at the end of December, it had grown to $3,030 (double the level of December 2022). And that is the advertised price before negotiations or hidden factory-to-dealer incentives - such as stair-step volume bonuses - are factored in.

Which vehicle segments are hot, and are not?

Perhaps the most flooded major segment, relative to sales, is that of full-size pickups (more on that below). Meanwhile, the compact SUV segment has the most inventory - but it's in line with overall industry growth - and with registrations humming along at about 200,000 per month, the C-SUV segment matches the ideal ratio of two months' supply.

As far as segments where one could argue there isn't enough inventory, the compact car, compact pickup, compact luxury SUV, and full-size SUV segments are tight on units advertised in dealer inventories.

Too many full-size pickups?

The full-size truck is a key profit generator for the Detroit 3. But when too many are on showroom floors, deep discounting happens in a rush. At the end of December, there were 307,000 full-size pickups available, up from 229,000 the same time last year. Meanwhile, the average MSRP has defied the industry trend, increasing to $63,000, from $59,300 in December 2022 and $55,400 at the start of 2022. But S&P Global Mobility analysis finds advertised discounts steadily increased all through 2023, with $4,740 the current average discount.

Average MSRP and list price, full-size pickup truck

Who is slashing their big pickup prices? Ram dealers, with 75% of dealer-advertised units below MSRP. The average discount is also sizably more than that of the tight pack of Chevrolet, GMC, and Ford. But even Toyota is discounting. Hot take? There is a lot of inventory out there…deals could be coming.

The mid-sized pickup battleground looming?

Toyota traditionally outsells its mid-size truck competitors handily. <span/>But with the redesigned 2024 Tacoma in factory ramp-up mode, and also in high demand, inventories plummeted through the fourth quarter. At the end of December, there were fewer Tacomas in dealer advertised inventory than Jeep Gladiator or Nissan Frontier. While Toyota dealers scramble to find units, might Jeep and Nissan dealers seize on the opportunity to conquest consumers who <span/>can't wait around for the new Tacoma?

EV inventories stabilizing

After growing through most of 2023, the end of December marked the first drop in inventory all year for Ford's Mustang Mach-E. But with Ford selling fewer than 5,000 Mach-Es in a month, there still is sizable backlog. A tougher tale to tell is F-150 Lightning, which despite cutting production has seen inventory grow from 3,200 units in August to 13,000 at the end of December. At least Ford is now selling lower-trim versions; the Lightning average MSRP is roughly $74,000, whereas in December 2022 it carried an average MSRP of $80,000 plus an $8,000 premium.

Other manufacturers are adjusting their EV inventories to acknowledge market realities. Most EV inventories - VW ID4 and Hyundai Ioniq, to name two leaders - have leveled off and are burbling along between 3,000 and 5,000 units for the last quarter or two, keeping pace with sales. The only real climber is the Chevrolet Bolt EV/EUV, but Chevy dealers also are adding more discounts on its compact EV. The key question still to be answered: Are we seeing suppressed EV sales due to a lack of inventory, or a lack of demand?
