Drivers cross over to crossovers

Americans bought a record 17.47 million vehicles in 2015, surging past the previous record of 17.35 million set in 2000. Several factors drove the record growth: pent-up demand, an improving economy, easy credit, low interest rates and low gas prices.

The last factor is affecting not only what vehicles we buy but also how automakers design future products.

Low gas prices have helped fuel the trend away from cars and into more trucks, SUVs and crossovers. Virtually every brand saw higher light truck sales, which includes pickups, vans, crossovers and SUVs, while cars were down. Crossover utility vehicle (CUV) sales are on fire. On the other end, fuel savers such as hybrids and electric cars, and even some conventionally powered economy cars, took an especially hard hit.

Considering these vehicles, as well as high-performance cars, were being developed when gas prices were oscillating at record highs between $3 and $4 in 2011 and 2012, according to Gasbuddy.com, may make it seem like automakers can see the future.

Instead, they see what consumers want.

"Fuel prices alone are not driving sales of trucks and SUVs," said Stephanie Brinley, senior analyst at IHS Automotive. "It's what the consumers prefer. Fuel economy is comparable with cars now, so you don't have the guilt. This just makes it easier."

Trucks in particular are known to be especially high-profit items for the manufacturers, so in the short term they will be happy to ride the wave. But in response to consumer trends and forecasts of low fuel prices in the near term, some brands are already cooling off car efforts and concentrating on truck and SUV development.

Ford announced at the 2016 Chicago Auto Show that it will add four more SUVs to its global lineup by 2020.

"In terms of a longer-term trend of people moving from passenger cars into SUVs, we think that will continue beyond fuel prices," said Mark LaNeve, Ford's vice president of sales and marketing, who cited improved powertrain efficiency of larger vehicles than in years past.

But automakers have to consider governmental pressure as well as consumer preference.

"Low fuel prices are here for the foreseeable future, maybe two years plus," said Wayne Gerdes, owner of CleanMPG.com. "However, much higher efficiency [CAFE] standards are still looming and the [automakers] have to meet or face large penalties."

Brinley said the Environmental Protection Agency "has signaled it's not relaxing their requirements for 2025." That magic number is an industry fleet average of 54.5 miles per gallon. The situation may not be as completely dire as it sounds, as Brinley points out this is an "unadjusted" number, and due to a complicated system of credits the manufacturers can take advantage of along with other factors, the requirement should end up "closer to 35 mpg real-world."

This prompted the drive to more fuel-efficient vehicles in the first place, when CAFE regulations were started in 1975 and finalized in 2012. As a result, larger vehicles are more fuel-efficient than ever before. A 1985 Ford F-150 2WD automatic got about 16 mpg combined; the 2015 version of America's best-selling vehicle gets 22 mpg combined.

Despite the improvement in fleet fuel economy, the biggest gainers of fuel efficiency are losing to low gas prices. The extra cost often associated with hybrid powertrains or battery electric vehicles are hard for buyers to justify with cheap gas.

"Something needs to give," Brinley said about the consumer disconnect between cheap gas and the need for more efficient, less polluting powertrains.

As far as what future trends to watch for, Brinley says look at the engineering under the skin for more fuel-saving tech, such as lightweight materials or multi­speed transmissions that are spreading into new models and segments.

Gerdes expects the trend to crossovers and trucks to continue, but to also expect more efficient options in those vehicles.
