A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Cars most likely to be involved in accidents

Data from Insurify shows which models have the most accident-prone drivers behind the wheel. It also shows the proportion of the drivers of said vehicles with an at-fault accident on record in the past seven years, based on Insurify’s analysis of over 4 million car insurance applications. For reference, the national average is 10.78%, and each of these vehiclesÂ’ drivers represent a statistically significant increase over that. Now, it would be easy to infer that these cars are dangerous, but such is not necessarily the case. Remember, drivers cause accidents, not cars. These just happen to be the cars that accident-prone drivers drive. YouÂ’ll notice that many are mainstream, affordable cars, often with decent crash ratings. Also keep in mind that vehicle accidents are up since the beginning of the pandemic, so no matter what you drive, please drive safely. 10. Hyundai Ioniq This affordable, electrified vehicle platform sneaks into this list with 14.45% of drivers with a recent at-fault accident on record. 9. Lexus CT Another hybrid, this Prius-powered Lexus beats the national average at 14.57%. 8. Toyota Prius V Yet another hybrid, the larger but discontinued member of the Prius family sees 14.72% of its drivers with recent accidents. 7. Mazda CX-3 The Mazda CX-3, which is discontinued for the 2022 model year, sees the accident-prone making up 14.9% of its drivers. 6. Infiniti Q60 The second and final luxury car on this list has more accident-prone drivers than average, at 14.93%. 5. Subaru Impreza The first of two Subarus on this list has 15.1% of drivers with recent accidents on record. 4. Hyundai Genesis Coupe The Genesis Coupe was only on the market for a brief span before it was discontinued and Genesis spun off into its own luxury brand. That said, it too beats the national average for accidents, at 15.29%. 3. Subaru WRX Despite its standard all-wheel drive, the boy-racer WRX has 15.44% of drivers with a prior accident in the last seven years. 2. Kia Stinger We love the Kia Stinger, and had great luck with our long-termer that graced the Autoblog garage for a year. That said, 15.75% of its drivers represent have a recent accident on record. 1. Scion FR-S This fun two-seater attracts the most accident prone drivers, with 15.87% with recent at-fault crashes.
