监管机构放弃54.5 mpg目标

2011年,环境保护署和其他几个政府机构同意对汽车制造商施加一套新的燃油效率标准。该标准规定,如果制造商想在美国出售汽车,那么他们的平均燃油燃油经济性(即其合并产品的平均MPG)必须为54.5 mpg。既定的目标是减少对化石燃料和改善空气质量的依赖。

这些标准现在已经被放弃,但不是因为汽车制造商无法生产燃油效率的车辆。相反,消费者偏爱SUV,卡车,跨界车和其他燃油汽车,因此平均的车队燃油消耗将无法达到54.5 mpg的目标。消费者根本不以机构官员预计的速度选择更高的汽车。

尽管如此,不可否认的是,燃料效率正在提高。代理商官员估计,2025年车型年,平均车队MPG在50至52.6之间。

More Car Breakdowns Than Ever in 2015: AAA

record car breakdowns

新车的技术和功能比以往任何时候都多。虽然小玩意在工作时很棒,但是当它们不按预期运行时,它们可能会给驾驶员带来重大问题。

The American Automobile Association (AAA) came to the assistance of 32 million drivers in 2015 – a record in their hundred-plus year history. Of those cases, vehicles less than five years old had an increased proportion of tire and key-related problems. AAA officials said that the low-profile tires in vogue for new vehicles are more susceptible to damage. Keyless ignition systems, which use wireless frequencies instead of a physical key to start an engine, can drain batteries if stored too closely to the car.

虽然看到年复一年地添加到汽车中的新功能令人兴奋,但该统计数据表明,驾驶员并没有快速适应技术升级的潜在陷阱。

VW’s Multi-Billion Dollar Dieselgate Settlement Gains Preliminary Approval

To get you up to speed, Volkswagen is in big trouble after it was discovered that cars with their TDI “Clean Diesel” engine used complex software to cheat emissions tests. The software worked to improve engine performance during emissions testing, but once back on the road TDI engines spewed out up to 40 times the permitted amount of greenhouse gasses.

现在,大众必须为所有者和政府监管机构赔偿造成的损害。主持此案的美国地方法院法官已对147亿美元的和解协议获得了初步批准,这是德国汽车制造商的重大打击,但也许对TDI司机有利。

The end of the “Dieselgate” scandal is far from sight. VW has yet to find for a permanent fix for their TDI cars, which are still on the road. It’s possible that VW will have to buy these cars back from owners.

Recall After Recall: Continued Trouble for Takata Airbags

目前,美国历史上最大的产品召回正在进行中,其中7000万辆汽车受安全气囊故障影响。这些由汽车零件供应商高田生产的安全气囊包含一种会随着时间的推移而降解的充气机。这意味着,如果发生崩溃,充气机单元可以向驾驶员爆炸并射击金属碎片。这些安全气囊至少有10人丧生,100多人受伤。

这种召回已经进行了几年,许多受影响的车辆已将其安全气囊取代。但是,这位前高田工程师负责设计和测试安全气囊充气机说,该公司继续在替代品中使用相同的挥发性爆炸物。他担心,由于这些据说安全的替换单位,会有另一种召回 - 可能会有更多的伤害和死亡。

可能会开放刑事调查,以仔细研究这种情况。就目前而言,驱动因素还没有太多来解决这个问题。我们建议使用NHTSA的召回检查员看看召回可能会影响您的车辆。

通用汽车在自主驾驶上减慢

在特斯拉的“自动驾驶”系统涉及几次备受瞩目的崩溃之后,围绕自动驾驶技术的争议最近引起了酝酿。这些事件正在调查中,但特斯拉坚决按预期工作,其他因素导致了坠机事故。

However, General Motors CEO Mary Barra says that her company will step back and take another “look at what technology is in the best interest of consumers.” This means that the release of GM’s Autopilot equivalent, dubbed Supercruise, will probably be delayed.

It seems that self-driving cars are the future, and it is true that carmakers like Tesla use real-world Autopilot data to continually refine the software – the more people use it, the better it gets. But now that the electric car company is accused of rolling out an unfinished and unsafe product, it makes sense that GM might prefer to wait to reveal Supercruise.

新的大运动是‘Vette

您是否曾经听过这样的说法:“快速驾驶慢速汽车比快速汽车慢速驾驶更有趣”?这个想法是,驾驶不太能力的汽车对驾驶员来说更具吸引力和涉及,而不是为驾驶员可能永远无法测试其极限的更强大的汽车而努力。

虽然没有雪佛兰Corvette的版本可以称为“慢”,但似乎雪佛兰在设计Corvette Grand Sport时,雪佛兰将这种骑车人的格言带到了心中。这款新的2017年修剪水平将标准Stingray和Bonkers 650马力Z06分开。

汽车新闻记者采用Stingray的460马力V8发动机以及许多以轨道为中心的Z06的底盘,悬架,制动器和空气动力学升级,因此汽车记者对这项宏伟的运动表示赞赏。他们说,这将(仍然非常强大)黄貂鱼的每日驾驶性与Z06的敏锐动力相结合。

像所有Corvettes一样,大型运动可作为双门轿跑车或可转换,具有手动或自动变速箱,在四秒钟内以每小时60英里的速度冲刺。不过,不要认为这仅适用于直线速度 - 大型运动已准备好迎接曲折的向后路和技术赛道。
