The sales trend of sedans being passed over for SUVs and crossovers has been obvious for a while, but market data is starting to prove just how severe the switch has been.
"After spending 20 of the last 27 years as the best-selling vehicle segment in the US, midsize sedans have taken a dramatic downward turn in popularity," consumer auto site Edmunds.com said in a statement.
According to the site, mid-size sedans — once mainstays in the US auto market for carmakers such as Honda and Toyotas — are in trouble, falling from the best-selling segment of vehicles in 2014 to number five in 2017.
"Market share for midsize sedans is now a meager 10.7 percent," Edmunds said, adding that the figure is the lowest since 1991 when the site began tracking data.
“While it’s common for consumer tastes to change over time, it’s surprising to see just how quickly shoppers have made the switch from sedans to SUVs,” Jessica Caldwell, Edmunds.com executive director of industry analysis, said in a statement.
"As recently as three years ago, the Accord made up nearly 30 percent of all of Honda’s sales in the US, and so far in 2017 it’s down to 22 percent. Now that shoppers can now get an SUV for a similar price as a sedan and not have to pay much more at the pump, it’s hard to convince them the smaller vehicle is a better choice."

A 1955 Ford Consul Convertible MK 1. The first post-war cars from Dagenham were almost identical to pre-war models, but the 1951 'Five Star Car' Consul/Zephyr range was revolutionary. With American-styled unitary bodies scaled down for European markets, the cars featured new independent front suspension by Earle MacPherson. Convertibles, which accounted for less than 2% of production, were developed by Carbodies of Coventry in 1953. Both the Consul and 6 cylinder Zephyr were popular among fleet users and hire companies. Ford production in Britain, began in a converted tram factory in Manchester in 1911, transferring to the purpose-built Dagenham factory in 1931.

A young man washes the family Ford Anglia car on an Essex estate in the early nineteen sixties. Bending down to wring a leather dry into a bucket the young man cleans his father's beloved Anglia in the street outside the family house which interestingly, is otherwise empty of other cars. This is the new age of car ownership when newfound wealth meant families could afford to buy a vehicle and travel elsewhere after the war years of 1950s austerity. The Ford Anglia is a British car designed and manufactured by Ford in the United Kingdom. The Ford Anglia name was applied to four models of car between 1939 and 1967. 1,594,486 Anglias were produced. The picture was recorded on Kodachrome (Kodak) film in about 1961.

The great debate
For the past two years, as auto sales in the US have boomed amid low gas prices, a debate has raged about whether automakers should remain committed to the traditional family sedan.
These vehicles are less profitable than pickup trucks and SUVs, so carmakers have been pleased to see consumers shift away from them — but challenged to decide whether the trend is cyclical or structural. Auto companies remember being burned badly in the early-to-mid 2000s when spiking gas prices sent buyers searching for cheaper-to-operate small cars and hybrids. SUVs were derided for being gas-guzzling dinosaurs.
A change in design and engineering created a new class of vehicles — SUVs built on more fuel-efficient car platforms — and customers have flocked to these so-called "crossovers."
The change has been so dramatic that big automakers have started to ask themselves whether they should discontinue sedan production altogether — or outsource it to markets where the vehicles are still favored, such as China, or where sedans are cheaper to build, such as Mexico.
Fiat Chrysler Automobiles has led the way here. While both General Motors and Ford are more or less staying the course with sedans, FCA is in the process of shifting US production to SUVs. CEO Sergio Marchionne is in the "structural change" camp and has been unflinching about how much pain carmaker will endure if they don't follow consumer demand.
