Jonny decides to draw comparisons between the Ford Mustang V8 and the Abarth 595 Competizione to find out whether or not size really matters. Ben sets Rob & Jonny a challenge that involves a trip to a scrapyard, and then bamboozles Jonny with a discussion on Elon Musk's boring company. Rob presents the second part of the film character fight to the death, with a guest appearance from Brum. Jonny previews his upcoming visit to Silverstone to drive some Radical cars, and the chaps receive another letter.
Jonny talks about his experiences in Germany with the new Honda Civic Type R, and also reviews the new Ford Fiesta after a brief trip to Spain. Ben asks about "Land of the Ancients" to great amusement while Rob tries to discuss phone data storage in rental cars. Finally, the chaps crack open the world of movies, to decide who will be the greatest film character in a fight to the death.
Rob reveals the outcome of his parking ticket from the last episode; Jonny discusses his experiences with the Aston Martin V8 and a longing for driving gloves; Ben brings up some options for more efficient battery charging for electric cars; and the chaps discuss Haynes Motor Museum and respond to a letter.
Jonny tells all about his experiences at an Abarth day at Rockingham and his time spent at Silverstone with Marco Mapelli and Attempto Racing; Rob and Ben report back on the selection of cars they drove at the 2017 SMMT Test Day; Ben discusses an app that he thinks may get people where they want to be, as well as where they need to be; and there's some sensitive material regarding parking tickets and death.
Smooth Traffic reaches episode thirty, and has a mini celebration by discussing anything that doesn't relate to being 30. Jonny talks briefly about the Audi TT RS, Ben brings up smart traffic lights from the USA, and Rob tries to keep order when the chaps reveal their highly spec'd cars that start under £25,000.
Jonny tells all about his recent exclusive encounter with the only Porsche 959 cabriolet in the world; the chaps discuss the Renault Kadjar and it's many interesting features; Rob sets the guys a challenge to spec up a cheap car for the next episode; Ben tries his hand at gameshow hosting once again; and there's the inevitable round of Deadliest Boot Spaces.
Jonny and Rob return with a special episode of Smooth Traffic to preview the 2017 Formula One season. In a similar format to last year, the guys will look at the teams and drivers, the 2017 calendar, and the big changes to the sport this season. As well as this, there will be ridiculously bold predictions and a complete absence of Ben.
Jonny shares tales of travelling within the former Yugoslavia while reviewing the brand new Nissan Micra; Rob blends together two regular Smooth Traffic features in order to talk about being a car collector; Jonny discusses an up-and-coming graffiti artist and tries to rally the nation; there's an unusual round of Deadliest Boot Spaces; and the chaps finally resort to toilet humour after Jonny has a new 'experience' in Europe.
The chaps discuss the Smooth Traffic Winter Road Trip 2017, while still on the trip! Comparisons are drawn between the new Subaru WRX STi and it's second generation Impreza predecessor. Rob and Ben both get some issues off of their chests, and there's another round of the missing word game, which still bares no resemblance to any other gameshow segment.
It's a news-heavy episode, as the guys discuss Bentley, Alfa & F1 news. Bentley's proposed fuel-concierge service is discussed, the reveal of the new Alfa Stelvio raises some differing opinions, and Nico Rosberg's decision to retire falls under the Smooth Traffic microscope. There's still time for Ben to rip-off a popular quiz show segment, for Jonny to make some slanderous comments, and for Rob to almost make it through the entire show without being baited by Jonny. Almost.
