Sami spends time with the weakest Mustang engine wrapped in the heaviest (convertible) body and attempts to convince Benjamin why that's not a completely terrible experience. He also samples the huge wing on the 2018 Subaru BRZ tS and pronounces it to be the next logical progression in the coupe's evolution - in a world where extra horsepower isn't available, of course. The pair then delve into the mailbag to respond to messages from readers about BMW, supercars, and more.

What happens when you swap a high-revving V8 for a twin-turbo V6? The 2018 Audi RS5 answers that question with surprising authority, according to Benjamin after he spend 1,000 miles behind the wheel delving into the soul of Audi's latest sports car. Sami decides it's time to ditch Germany and embrace Sweden (by way of China) if you're in the market for a small luxury SUV as he throws his weight behind the 2018 Volvo XC40 versus the 2018 BMW X1. Finally, the pair enjoy some autonomous car schaudenfreude courtesy of Goodwood.

Is driving the 2018 Lamborghini Aventador S roadster a life-changing experience? According to Sami, the answer is yes - with a few caveats. Benjamin drives a pair of down-to-Earth Minis - the Cooper and the Countryman - that booked the Mini universe in terms of both price and size. Finally, both Benjamin and Sami get deep into the revelation that the Challenger Hellcat is gaining a new family member - the Redeye - and that some old favorites are getting a host of upgrades and changes.

Do you need a 475 horsepower, track-ready SUV? Does anyone? The 2018 Dodge Durango SRT gets road-tested by both Benjamin and Sami this week, who are both in love with its exhaust note and appalled by its fuel economy. Sami also ponders the missed opportunity that is the 2018 Chevrolet Tahoe RST, the 'performance' edition of the Durango's direct competitor that leaves a lot on the table. The pair also provide final thoughts on the departing 2018 GMC Sierra Denali, what it's like to attend the Bob Bondurant driving school with Bill Goldberg, and why a robot like the Honda Asimo gets to retire at the age of 18.

What's it like driving the 2019 Audi Q8 across the driest desert on the planet? Benjamin has the scoop after piloting the Q8 through Chile's Atacama, which NASA uses as a stand-in for the surface of Mars. Closer to home, Sami is impressed by how well Subaru has nailed its second attempt at a seven-seat crossover with the 2019 Subaru Ascent, which he drove along the Cape Breton coast. Finally, Benjamin drives one of this heroes - the bonkers Renault Clio V6 - and Sami is sad about the recent reveal of the Chevrolet Blazer.

The 2018 BMW 640i Gran Turismo is perhaps the most bizarre BMW also built - and yet, somehow, perhaps the most useful vehicle in the company's current line-up. Both Benjamin and Sami have their minds completely blown by this baffling, and amazing, automobile. Also on deck: Sami spends a week with the 2018 Jeep Grand Cherokee, and the pair try to figure out who, exactly, needs to order Applebees directly from their car's touchscreen, which you can now do in a brand new Hyundai, and why Porsche named the Mission E the 'Taycan.'

Would you buy a diesel pickup? What about a diesel pickup that's smaller than a full-size? And would you pay $50,000 for it? These are the questions Benjamin tries to answer when driving the 2018 GMC Canyon Diesel over the course of a week. Sami, when not provoking Benjamin about how many tires he's hauling around, also chips in with his thoughts on the 2019 Kia Sorento redesign, before wrapping things up with listener questions.

Does the 2019 Lexus ES still have a place at the table in a world where mid-size premium sedans offering tons of luxury features can be had from nearly every automaker on the market? Benjamin and Sami discuss the all-new ES after having put it through its paces.

When is weird too weird? When is weird not enough? That's what Sami attempts to discover when comparing the 2018 Kia Soul crossover to the 2018 Toyota CH-R. Benjamin jumps in with his strangely authoritative opinions on why, exactly, a whole bunch of other strange-looking SUVs failed where the Soul has succeeded. He then talks about his time driving the twin-turbo rotary-powered FD Mazda RX-7 from the Mazda classic collection, while Sami quietly seethes with jealousy.

Is the 2018 GMC Sierra Denali falling behind the pack just prior to its complete redesign this fall? After towing with it this past week, Sami certainly thinks so - especially compared to the 2018 Ford F-150 that Benjamin was driving. The pair also discuss their shared time in the 2018 Volvo S90 T8, debate the merits of its battery power, and try to figure out why Sami is so in love with the red convertible top on the 2018 Mazda MX-5 Miata.
