Average new-car fuel economy figures continue record pace

Manufacturers are making more efficient cars and trucks; we've known that to be true for some time. Nearly every new car has some sort of trick to eke a few extra miles out of every gallon of fuel. Whether that be turbocharging, active aerodynamics or hybrid technology/electrified powertrains, the fact is that our vehicles are more efficient than ever before.
Thanks to a recent study by TrueCar, we've got fresh quantitative data to support the above statements. For the fourth month in a row, we've seen an improvement in national fleet fuel economy. We Americans are 0.7 miles per gallon more efficient than we were last month, and our cars are 1.6-mpg better than at this time last year. That said, we're still down on 2013's high, which was set back in January at 24.5 mpg.
Not only does this reflect the improved technologies in our vehicles, but it demonstrates a changing mindset among consumers, who are purchasing more efficient vehicles despite the relative stabilization of fuel prices. Every fuel-efficient model sold drives its manufacturers fleet average up.

McLaren working on P15 supercar to slot between 650S and P1

McLaren has been busy these past few years. It launched the MP4-12C in 2011, the 12C Spider in 2012, the P1 in 2013 and (most recently) the 650S in 2014. But it's not about to stop there. It's got an "entry-level" model in the works, set to take on the Porsche 911, and - according to information reported by Car and Driver and confirmed by McLaren in correspondence with Autoblog - a new flagship model, too.
The project is internally codenamed P15, and it calls for a new flagship that will cap the company's lineup once the P1 finishes its limited production run, but carry a price tag in the neighborhood of $500k to slot in between the P1 and the new 650S.
Just how, you wonder, can McLaren possibly develop another supercar each year? Simple: underneath, they're all essentially the same. (Only we're sure it's anything but simple.) That is to say they're all based on the same carbon monocoque structure and powered by the same 3.8-liter twin-turbo V8 mated to a seven-speed dual-clutch transmission driving the rear wheels. What differentiates them is what the engineers in Woking build around that monocoque and how they tune the engine: +/- 600 horsepower in the 12C (depending on the year it was built), 640 hp in the 650S, or 727 hp in the P1 (with another 177 from the electric assist). The 911 fighter would likely develop in the 500hp range, and the P15 will probably land in the upper 600 (or lower 700) range.

Brand new cars are being sold with defective Takata airbags

If you just bought a 2016 Audi TT, 2017 Audi R8, 2016–17 Mitsubishi i-MiEV, or 2016 Volkswagen CC, we have some unsettling news for you. A report provided to a US Senate committee that oversees the US National Highway Traffic Safety Administration (NHTSA) and reported on by Automotive News claims these vehicles were sold with defective Takata airbags. And it gets worse. Toyota and FCA are called out in the report for continuing to build vehicles that will need to be recalled down the line for the same issue. That's not all. The report also states that of the airbags that have been replaced already in the Takata recall campaign, 2.1 million will need to eventually be replaced again. They don't have the drying agent that prevents the degradation of the ammonium nitrate, which can lead to explosions that can destroy the airbag housing and propel metal fragments at occupants. So these airbags are out there already. We're not done yet. There's also a stockpile of about 580,000 airbags waiting to be installed in cars coming in to have their defective airbags replaced. These 580k airbags also don't have the drying agent. They'll need to be replaced down the road, too. A new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time. If all this has you spinning around in a frustrated, agitated mess, there's a silver lining that is better than it sounds. So take a breath, run your fingers through your hair, and read on. Our best evidence right now demonstrates that defective Takata airbags – those without the drying agent that prevents humidity from degrading the ammonium nitrate propellant – aren't dangerous yet. It takes a long period of time combined with high humidity for them to reach the point where they can rupture their housing and cause serious injury. It's a matter of years, not days. So a new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time – and six years seems to be about as early as the degradation happens in the worst possible scenario. All this is small comfort for the millions of people who just realized their brand-new car has a time bomb installed in the wheel or dashboard, or the owners who waited patiently to have their airbags replaced only to discover that the new airbag is probably defective in the same way (although newer and safer!) as the old one.
