Check out Harry Metcalfe's 1978 Jaguar XJ 5.3 V12 Coupe

Jaguar may have built its business producing luxury sedans, but it also made some superb coupes over the years, from the XK120 through the E-Type, XJS and XJ220 to today's F-Type. The automaker has largely steered clear of turning its four-door models into two-doors, but there was a time when it did exactly that. And Harry Metcalfe, former editor of the British car magazine Evo, just happens to have one in his garage. Based on the Series II XJ sedan, the XJ Coupe was long and elegant – something along the lines of what you might see today in the form of the Mercedes S-Class Coupe, but smaller and built the better part of four decades ago. With only around 10,000 of them made, the pillar-less XJ-C was much rarer than the more iconic E-Type, and even fewer of them packed the 5.3-liter fuel-injected V12 engine. That makes the former Evo editor's ride a rather scarce one indeed, and well worth checking out in his latest video clip.

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.

Jaguar F-Type squares off against Porsche 911, Aston V8 Vantage with Chris Harris

Chris Harris is back on the job, taking on really really difficult car questions like: Which enormously sexy and good-to-drive, high-performance convertible is the top of the heap? As one of the hottest cars in the luxury space right now, the Jaguar F-Type S is, of course, in on the action. Competition comes in the form of the Aston Martin V8 Vantage Roadster and the Porsche 911 Carrera S Cabriolet. Sun-loving CEOs who despise test-driving need look no further.
Scroll on below for a fully featured (with a running time of more than 20 minutes) comparison video. Harris does his best to entertain - in a typically nitpicky and made-up-British-words fashion - and the moving pictures are lovely to look at. Kick back, pour a pint and get your weekend started off right.
