Audi S4 drivers are the most accident-prone, insurance report says

Culling data from more than 4.6 million automobile insurance applications, researchers at the Insurify insurance comparison marketplace picked a winner — or more to the point, a loser — in its determination of the car model with the most accidents so far in 2023: the Audi S4. Why does the sporty, luxury-class German sedan rank so high (or so low)? The organization found that S4 drivers, piloting a car with almost 350 horsepower, are among those who collect the most speeding tickets, and that they get into accidents at a rate 54 percent higher than the national average. If the S4 isnÂ’t a surprise with an at-fault accident rate of 11.7 percent, consider the “family friendly” brand that appears three times on the Insurity list: Subaru. It is represented by three models, including the turbocharged WRX and XV Crosstrek, and at the better-performing bottom of the list, the Subaru Impreza, with an accident rate of 10.3 percent.  In 2023, 7.6 percent of U.S. drivers were involved in at least one at-fault accident in the prior seven years. For drivers of cars on this list, the average at-fault accident rate was 10.5 percent, meaning these drivers are 1.4 times as likely to have an at-fault accident on record. According to its statement, the Insurity data science team explored key safety features, driver behavior, and Insurance Institute for Highway Safety (IIHS) evaluations to pinpoint possible reasons behind these carsÂ’ high accident rates. Following is the list, counting down to the models with most reported accidents: 10. Subaru Impreza (percentage of drivers with a prior at-fault accident on record: 10.3 percent; MSRP base model): $19,795) 9. Kia Niro (percentage of drivers with a prior at-fault accident on record: 10.4 percent; MSRP base model): $26,590) 8. Chevrolet Silverado LD (percentage of drivers with a prior at-fault accident on record: 10.4%, MSRP base model): $34,500) 7. Subaru XV Crosstrek (percentage of drivers with a prior at-fault accident on record: 10.5 percent, MSRP 6. Subaru WRX.(percentage of drivers with a prior at-fault accident on record: 10.7% MSRP base model): $29,605) 5. Toyota GR86 (percentage of drivers with a prior at-fault accident on record: 10.8 percent MSRP base model): $29,900) 4. Hyundai Veloster N (percentage of drivers with a prior at-fault accident on record: 10.9 percent; MSRP base model): $32,500) 3.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Car and Driver reveals spy shots of mid-engine 2017 Corvette

Some news in the car world is perennial, and some is perennially wrong. Typically news about some upcoming mid-engined Chevy Corvette has fallen into the latter category, with rumors never yet generating a road car. This time could very well be different. Car and Driver has some exclusive photographs of what would appear to be a Corvette test mule with a mid-mounted engine. The car in question might look like a Holden SSV ute that's undergone some indelicate modification, but C/D editor Don Sherman assures that the bones of a C8 'Vette live within that crude bodywork. Sherman points to the closeness of the cabin to the front axle as clue number one of this car's mid-engine attitude, as well as the powertrain-sized space between the back of the seats and the rear axle. The roof and glasshouse are all clearly plucked from the current C7, and the gas tank filler positioned on the B-pillar is another huge clue. The buff book estimates that the mule points to a timeline for sale, even. Testing on this level could mean a mid-engined C8 ready for sale in as few as 20 months, or for the 2017 model year. Click over to Car and Driver to have a close look at this important set of spy photographs, as well as a rendering of what a finished C8 might ultimately look like
