U.S. auto sales in April expected to drop despite big discounts

DETROIT — U.S. auto sales in April likely fell nearly 8 percent from the same month in 2017 despite big discounts for consumers, industry consultants J.D. Power and LMC Automotive said on Thursday. For much of the past two years, the discounts offered by automakers have remained at levels that industry analysts say are unsustainable and unhealthy in the long term. April U.S. new vehicle sales will likely be about 1.31 million units, down from 1.42 million units a year earlier, the consultancies said. The forecast was based on the first 17 selling days of April. Automakers, including Ford and Fiat Chrysler Automobiles, will release April U.S. sales results on May 1. Earlier this month, No. 1 U.S. automaker General Motors said it will stop reporting monthly U.S. sales because the 30-day snapshot does not accurately reflect the market. GM will instead issue quarterly sales reports. U.S. new vehicle sales fell 2 percent in 2017 to 17.23 million units after hitting a record high in 2016. Sales are expected to drop further in 2018 as interest rates rise and more late-model used cars return to dealer lots to compete with new ones. LMC expects full-year 2018 U.S. new vehicle sales to come in at around 17 million units. "Uncertainty and unfavorable factors appear to be mounting for autos, including a volatile stock market, rising interest rates, rising oil prices and potential trade roadblocks," Jeff Schuster, LMC's head of global vehicle forecasts, said in a statement. The seasonally adjusted annualized rate of sales for April will be 16.6 million vehicles, down more than 2 percent from 17 million units in April 2017, the consultancies said. Retail sales to consumers, excluding lower-margin fleet sales to rental agencies, businesses and government, were set to decline about 9 percent in April. The level of consumer discounts, which can erode profit margins and undercut resale values, "remains the larger concern," the consultancies said. The average discount was $3,698, up $187 from April 2017. Discounts on trucks and SUVs were up $426, but down $226 on passenger cars.

Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.
