Hello! It's time for the TTAC podcast!


On this week's TTAC podcast we talk about reliability with Mazda's Jon Leverett. We also chat NASCAR and headlight bulbs with TTAC contributor Matthew Guy.

We dig into how automakers test their cars, NASCAR's first-round playoff at Darlington, and how to keep your lights shining bright.

You can find us wherever you get your podcasts or by clicking  here. If you like what you hear, please leave a review!

We thank Jon Leverett and Matthew Guy for their time, and we thank Matt Posky for editing. Most of all, we thank you for listening!

We’ll see you next time!

Tim Healey grew up around the auto-parts business and has always had a love for cars — his parents joke his first word was “‘Vette”. Despite this, he wanted to pursue a career in sports writing but he ended up falling semi-accidentally into the automotive-journalism industry, first at Consumer Guide Automotive and later at Web2Carz.com. He also worked as an industry analyst at Mintel Group and freelanced for About.com, CarFax, Vehix.com, High Gear Media, Torque News, FutureCar.com, Cars.com, among others, and of course Vertical Scope sites such as AutoGuide.com, Off-Road.com, and HybridCars.com. He’s an urbanite and as such, doesn’t need a daily driver, but if he had one, it would be compact, sporty, and have a manual transmission.

    I would expect that reducing the number of drivetrain moving parts by 97% would help with reliability.

    Nothing trail-blazing.


    Stick to an older powertrain that has had all the kinks worked out

  • Rrp138519787 If Jeep wanted to re-introduce the Wagoneer name, they just should have named the Grand Cherokee L the Wagoneer instead, and done a little bit more styling differentiation. They could have done a super deluxe version as the Grand Wagoneer. But all Wagoneers would have been the three row version as the primary product differentiation. And would cause less confusion for consumers overall.
