40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.

2017 Audi Q7 starts at $55,750

The second-generation Audi Q7 debuted last winter, and we already drove it in the spring in Europe. Audi, however, kept US pricing for this lighter, more stylish luxury SUV a secret – until now. The 2017 Q7 starts at $55,750 (including the $950-destination charge), and that's over $6,500 more than the $49,225-base cost for the last-gen 2015 model (there was no 2016 version in the US). Buyers get some big updates when they pay the extra cash for the 2017 model. The switch to the MLB platform helps cut 475 pounds, and aluminum suspension components reduce unsprung mass. Audi's Pre Sense City safety system comes standard and can automatically begin braking the seven-passenger SUV if a crash seems imminent below 52 miles per hour. Three-zone automatic climate control and a panoramic sunroof are also on the normal features list. The options include high-tech upgrades like the company's virtual cockpit system, a color head-up display, and a 23-speaker Bang & Olufsen stereo. Audi's 3.0 TFSI V6 with 333 horsepower and 325 pound-feet of torque and an eight-speed automatic is the only available powertrain combo for the Q7 in the US. Audi originally planned to offer the 3.0-liter TDI V6, but emissions problems nixed that. The second-gen Q7 is available in three trim levels here: Premium, Premium Plus for $59,750, and Prestige for $65,250. Company spokesperson Amelia Fine-Morrison tells Autoblog the first 2017s will arrive at dealers in January.
