With fewer than 15,000 cars sold in the US last year, the brand lived almost purely on provenance-its storied history and the occasional Bond film.
It takes Ford less than three days to move that much metal. Jaguar engineers, however, weren't idle. They were busy drastically overhauling the lineup.
Car executives spend a lot of time talking about "product cadence," the art of pacing precisely when to pull the cover off new models.
Typically, they try to spread out big and exciting new looks to smooth demand and design resources. Jaguar did the opposite.
The brand overhauled its entire lineup in less than a year, rolling out a new version of its midrange XF sedan in November, followed a few months later by an updated XJ, its most expensive sedan.
In May, US dealers started selling two all-new models, the entry-level XE sedan and the F-Pace, Jaguar's first SUV.
It was a blitz of metal-based marketing that appears to be working handsomely.
"I think from a normal perspective you want to have a more staggered approach," Joachim Eberhardt, the North America unit's chief executive, told us in September. "But what we're trying to do here is grab the attention of the marketplace."
The F-Pace in particular has been a hit. The midsize SUV has garnered breathless reviews while parking neatly in the hottest segment of the US market. If fancy, family trucks are wrong, Americans don't want to be right.
Foot traffic in dealerships has more than tripled.
The F-Pace rolled into US dealerships in May and immediately became Jaguar's bestseller. Last month, the little Costco-pod accounted for half of Jaguar transactions.
Demand has also been primed by some price cuts. The XF, Jaguar's midrange sedan, now starts at $51,900, 9 per cent less than it used to. And with a starting price of $34,900, Jaguar's starter XE sedan is cheaper than anything it has hawked in years.
Sales, of course, is an imperfect metric. It's an easy data point to inflate by sacrificing profit or gamesmanship. What's notable, however, is that while Jaguar cut prices, it also axed incentives.
Its incentive spending was almost one-third lower last month than it was in July 2015. It put just $4,016 on the hood of every Jaguar-less than almost every brand in the luxury car game.
