Autoblog Podcast #390

Episode #390 of the Autoblog Podcast is here, and this week, Dan Roth, Steven Ewing and Sebastian Blanco from Autoblog Green talk about the 2015 Ford Mustang specs, the 2016 Smart models, a proposal to add real-world numbers to EPA economy tests and the potential downside of autonomous cars. We start with what's in the garage and finish up with some of your questions, and for those of you who hung with us live on our UStream channel, thanks for taking the time. Check out the new rundown below with times for topics, and you can follow along down below with our Q&A. Thanks for listening!

2014 Audi Q5 TDI

I've struggled with diesel technology. It's not that I have a problem with it or dislike it, but rather that I don't particularly understand what stops its wider-spread adoption. Sure, memories of rust-prone, smoky, sluggish and uneconomical Oldsmobile diesels aren't exactly easy to erase from the collective memory of the North American motoring public, but I'd think that a few years into the latest crop of clean diesels, there'd be wider adoption - or at least consumer consideration - by now.
Part of the issue is the still limited number of segments that diesels are available in. The Volkswagen Golf/Jetta TDI is finally getting a challenger in the form of the Chevrolet Cruze Diesel, and the BMW 328d is bringing something new to the entry-level sports sedan, but there are still a huge group of segments where diesel-power has no representation.
The small, luxury crossover realm is not one of those. It has the Mercedes-Benz GLK250 Bluetec, a stylish crossover with a silky-smooth 2.1-liter, turbodiesel four-cylinder that can return the kind of fuel economy that makes people take notice. And while the GLK250 is quite good, economy will only spread the diesel's appeal so far. People need to experience the seat-flattening torque that these mills can produce, and for that, we most humbly recommend the new 2014 Audi Q5 TDI.

Audi SQ7 TDI packs 48V electric compressor, 664 lb-ft

Take a look at the new Audi SQ7 TDI. It's the first time Audi has done an S performance version of its flagship sport-ute, and packs under the hood a 4.0-liter V8 turbo diesel engine mated to an eight-speed automatic and all-wheel drive. It produces a potent 435 horsepower, and an absolutely bonkers 664 pound-feet of torque. The Audi SQ7 TDI produces a massive 664 lb-ft of torque. Impressive as it is, though, that doesn't even tell the full story. That's enough to make us forget it wasn't there in Geneva. It's also more torque than just about anything the Volkswagen Group makes – short of the Bentley Mulsanne Speed and the new Bugatti Chiron. Not even the Lamborghini Aventador SV or Bentley Continental GT Speed can touch that torque figure. Nor can competition like the Porsche Cayenne S Diesel (with its 385 hp and 627 lb-ft) or the BMW X5 M50d (381 hp and 546 lb-ft). It may not surpass the old twelve-cylinder Q7 6.0 TDI (with its 493 hp and 738 lb-ft), but still trounces the VW Touareg V10 TDI (309 hp and 553 lb-ft) – which was strong enough to tow a jet airplane, while the new SQ7 is fast enough to out-drag one (as you can see from the video below). Impressive as it is, though, that headline-grabbing torque figure doesn't tell the full story. To get there, Audi employed two conventional, sequential turbochargers and a third compressor that – in an industry first that's been a long time coming – is powered electrically. The engineers in Ingolstadt installed a beefier 48-volt electric subsystem to power the electric compressor (among other systems) and its latest valvetrain tech for the first time in a diesel. The result, Audi says, is a lack of any perceptible turbo lag – and a 0-62 time quoted at 4.8 seconds, en route to the typical electronically limited top speed of 155 miles per hour. As if that weren't enough, Audi also equipped the SQ7 TDI with an optional suspension package that coordinates the activities of three systems. There's a differential, a four-wheel steering system, and a clever electromechanical roll stabilization system that employs an electric motor (made possible once again by that 48-volt system) and a three-stage planetary gearbox to keep it all level and improve ride quality over rough surfaces. The sum total is an impressive technological tour de force on Audi's part, but one that we may just have to admire from afar.
