Jaguar designs Tour de France racing bike [w/video]

Jaguar is known for designing luxury sedans, and it's known for designing GTs. But once in a while it dabbles in a new area of transportation design. It's working on its first crossover at the moment, and even did a speedboat concept a couple of years ago. Now it's turned its attention to bicycles.
While many automakers have designed bikes in the past, Jaguar's project has a bit more of a direct correlation. It's been working with Team Sky - the outfit that has won the Tour de France two years running now - since 2010, furnishing the team with support vehicles for bicycle races around the world. But now it's stepping its collaboration up a notch by redesigning the team's bike.
Working with frame manufacturer Pinarello, Jaguar took the existing Dogma 65.1 racing bike design back to the drawing board. Jaguar's designers and engineers reshaped the frame tubes, seat post, front fork, derailleur and all the components attached to the frame, each part streamlined for aerodynamic efficiency. They ran it through Jaguar's Computational Fluid Dynamics processor 300 times then verified the results in the wind tunnel.

Lister reveals first continuation Knobbly roadster at Autosport

It's been over a year since we reported on a plan to revive Lister Cars, and now the storied British racing constructor has revealed the first production continuation example of its legendary Knobbly roadster. Built to the same specifications as the original from 1958, using the same drawings and equipment, the reborn Knobbly features aluminum bodywork and a race-prepped 3.8-liter straight six out of a Jaguar D-Type and producing 330 horsepower. Revealed at the Autosport International race car show in Birmingham, the new Knobbly arrives on Lister's 60th anniversary and less than a month after the passing of its founder, Brian Lister. Only ten examples like this one will be built, all of which have already been spoken for, prompting Lister to consider an additional three examples. Each is eligible under FIA regulations to compete in vintage racing events, with performance specs quoting a 4.3-second 0-60 time and a top speed of 181 miles per hour. LISTER CARS' REBORN 'KNOBBLY' MAKES PUBLIC DEBUT AT AUTOSPORT INTERNATIONAL - Lister Cars' reborn 'Knobbly' racer has made its public debut at Autosport International - Built to the very same specification as the original 1958 'Knobbly' it uses the late Brian Lister's original drawings and manufacturing jigs - Lister has received an overwhelming response to its limited run of ten continuations and order books are full - Lister Cars is now considering creating three individual final editions each celebrating the racing pedigree of the 'Knobbly' in a unique and memorable way Lister Cars' reborn 'Knobbly' racer has made its public debut at Autosport International at the NEC Birmingham. Celebrating Lister's 60th anniversary, the reborn 'Knobbly' is built to the very same specification as the original 1958 'Knobbly', using the late Brian Lister's original drawings and manufacturing jigs. It is powered by a race-prepared Jaguar D-Type 3.8-litre straight-six, producing 330bhp. All 'Knobbly' models are built at Lister Cars' Cambridge factory to meet relevant FIA racing regulations, with owners able to compete in a series of Lister historic race meetings planned during 2015. Despite following an original design laid out more than 55 years ago, the reborn 'Knobbly' has performance to match modern sports cars; it can accelerate from 0-60mph in 4.3 seconds and hit a top speed of 181mph. Lister Cars has already received an overwhelming response to its limited run and the 10 cars are now sold out.

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.
