David Brown Speedback GT marks US debut at The Quail

The British invasion has officially deployed another expeditionary force to these American shores with the arrival of the David Brown Speedback GT. The classically styled English grand tourer debuted nearly a year and a half ago, and has been racking up orders from discerning customers in the UK and across continental Europe. As promised, it has now made its American debut at the swanky Monterey event known as The Quail, A Motorsports Gathering. The Speedback GT is a coachbuilt grand touring coupe made by British startup David Brown Automotive. It's based on a Jaguar XKR, but reskinned inside and out to give it the look and feel of a classic Aston Martin – little wonder given the name it shares with the former Aston chief whose initials still adorn the DB model line. Underneath the retro bodywork lies Jaguar's celebrated 5.0-titer supercharged V8, giving the Speedback thoroughly modern levels of muscle with 510 horsepower and 461 pound-feet of torque. The resulting 0-60 time of 4.6 seconds and top speed of 155 miles per hour are suitably quick – not quite time-warping, but the performance is certainly nowhere near as old-school as the design would lead you to believe. Call it the best of both worlds, then, if you dig the styling. But don't expect everyone to be jumping on this particular gentlemanly bandwagon. At nearly half a million pounds sterling – over $750k at current exchange rates – it's sure to keep out the riffraff of which "the rest of us" are most certainly part.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

2017 Jaguar XE 20d Quick Spin

Base models rarely get their due in the press. Big-engine, high-horsepower variants get all the headlines, but the junior version is what sells in volume. We're just as guilty here at Autoblog, with both a first and second drive of the Jaguar XE in supercharged V6 guise, and barely a mention of the entry-level, 2.0-liter diesel. So, in Perd Hapley style, the Jaguar XE diesel is the model of the Jaguar XE we're going to discuss. Yes, the volume model of the Jaguar XE is a diesel, at least for now. A turbocharged 2.0-liter gas engine, wearing the 25t badge, will arrive after the XE's early 2016 on-sale date. Oil-burners and volume are not a thing in the United States, except for heavy-duty pickup trucks. Despite that apparent contradiction, the XE 20d could find some converts. Driving Notes The biggest clue to the engine's fuel source is the tachometer, which only counts to 6,000. But you wouldn't know from the fast throttle response or the way revs climb when you mash the accelerator. All 180 peak horsepower come at 4,000 rpm, and the 317 pound-feet of torque are available from 1750 to 2500 rpm. Really, this engine is smooth. Credit the low 15.1:1 compression ratio, which also helps make the engine's aluminum construction possible. The surge of power from the turbo builds steadily instead of kicking in all at once. Jaguar's engineers focused on friction reduction with a fanatical devotion, all in the name of efficiency. One key feature is the offset crankshaft. That is, the crankshaft is located to the side of the cylinder centerline. This reduces the side load forces during the firing cycle. In the manual transmission the gears are cupped to reduce mass. A pump sprays oil directly on the cogs, which cuts back on the total amount of fluid and cuts back on friction loss due to windage. No, the manual transmission isn't coming to the US. And yes, it's really good. Not just in the cliche journalist love for the diesel-manual combo, but objectively good. That smooth responsive nature of the engine is amplified when you get to choose your own gears. So we make due with the eight-speed automatic, the 8HP45 version of the ubiquious ZF box. The coolest trick here is a pendulum-style damper in the torque converter instead of a typical spring damper. When the torque converter is locked up this cuts down on torsional vibration between the engine and transmission. And that enables low-rpm cruising and higher mpg.
