Xcar focuses on famed Jaguar test driver Norman Dewis

If you have any interest at all in motoring history, especially when it comes to European sports car racing from the '50s and '60s, do absolutely whatever you can to set aside 38 minutes for this interview with former Jaguar test driver Norman Dewis from XCar. Dewis had a hand in developing the British brand's vehicles from 1952 to 1985, and as expected over that time, he amassed some fantastic stories. Xcar did a great job of teasing a few of those great tales out of him here. From the very beginning, Dewis was gifted with a natural talent to read a car as a test driver. When he was just 16, he was taken out on his first chance to evaluate a vehicle and picked out even more intricacies than his instructor. Dewis eventually wound up at Jaguar, and that's where his career really took off. Among his many accomplishments there, he had a role in developing disc brakes both for racing and the road, set multiple world top speed records, and helped bring the E-Type to the world. Dewis even made the famous overnight drive in an XKE convertible from England to display it at the Geneva Motor Show. Dewis tells a first-hand account of being in the Jaguar paddock during the tragic accident during the 1955 24 Hours of Le Mans that took the lives of dozens of spectators. It's a story that we usually can only read about or watch in black-and-white films. Hearing Dewis' side really brings this history to life.

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.

Top Gear caught filming Best of British near Buckingham Palace

YouTuber and car-fan extraordinaire Shmee probably had very little trouble tracking down the Top Gear film crew recently, as the group was putting together an episode that could accurately be described as "excessive." With its flag-waving (literally) Best of British theme, the TG guys gathered a jaw-dropping array of British cars, and parked them all right in front of Buckingham Palace to make extra sure that the point was driven home.
Top Gear hosts Jeremy Clarkson, Richard Hammond and James May were outfitted with a trio of Jaguar F-Types festooned with gigantic Union Jacks, with which to survey the landscape of British motoring glory. In the video below, you'll see that this includes any number of Mini, Aston Martin, Lotus, McLaren, Land Rover, Bentley and Rolls-Royce models (just to name a few), as well as a healthy dose of weird stuff that most people would never guess at being built in the UK. The lawnmowers and military vehicles are especially cool.
