Autoblog Podcast #339

Farewell, Zach Bowman; Pikes Peak 2013; Datsun; 2014 Ram lineup
Episode #339 of the Autoblog Podcast is here, and it's the last rodeo for Zach Bowman before he departs for other pastures. The crew this week consists of Dan Roth, Zach Bowman and Jeff Ross, who talk about the astounding records set at this year's Pike's Peak hill climb, the return of the Datsun brand name and the recently-announced 2014 Ram truck lineup. Of course, we start with the garage and end with your questions and comments. For those of you who hung with us live on our UStream channel, thanks for taking the time. You can follow along after the jump with our Q&A. Thanks for listening!
Autoblog Podcast #339:

Has the Jaguar XKR-S Sportbrake leaked out early?

Want to haul ass down the Autobahn with the whole family and all their gear in tow? Forget that Porsche Cayenne or Jeep Grand Cherokee SRT8 - what you'll want is a power wagon: something like an Audi RS6 Avant or Mercedes-Benz E63 AMG Estate. Unfortunately there are precious few of these performance station wagons on the market anywhere, especially with American offerings like the Cadillac CTS-V Sport Wagon on its way out and the Dodge Magnum SRT8 long gone. But there's a new challenger emerging.
That'd be the Jaguar XFR-S Sportbrake, a hi-po estate from Coventry that's been a long time in the making. And now it's apparently almost here. (Only by "here," we mean "there," as it's not likely ever to come to the United States.)
Apparently set to be unveiled at the Geneva Motor Show is a Frankenstein-style cross between a Jaguar XF Sportbrake and XFR-S performance sedan, taking the best elements from both. From the former, that means the extended roofline that gives it the cargo capacity of a small crossover. From the former, that means a 5.0-liter supercharged V8 producing 542 horsepower and 502 pound-feet of torque, driving the rear wheels through an eight-speed automatic transmission.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.
