Driving Jaguar's Continuation Lightweight E-Type

Something has happened to sports cars over the past 15-20 years. While reaching ever-higher levels of quantitative dominance the driving experience continues to become more sterile. Stability control, torque vectoring, variable electronic steering racks, lightning-quick dual-clutch automatic transmissions – all these make it easier to harness more power and drive faster than ever before. And yet too often it feels like something is missing. There is a growing divide between the capabilities of the modern performance car and the driver's sense of connection to the experience. In an era like the one we're in now, the Jaguar Lightweight E-Type hits you like a slap in the face. The story of the Lightweight E-Type goes back to 1963, when Jaguar set aside eighteen chassis numbers for a run of "Special GT E-Type" cars. These were factory-built racers with aluminum bodies, powered by the aluminum-block, 3.8-liter inline-six found in Jaguar's C- and D-Type LeMans racecars of the 1950s. Of the eighteen cars slated for production, only twelve were built and delivered to customers in 1964. For the next fifty years, those last six chassis numbers lay dormant, until their rediscovery a couple of years ago in a book in Jaguar's archives. In an era like the one we're in now, the Jaguar Lightweight E-Type hits you like a slap in the face. Jaguar Heritage, a section of Jaguar Land Rover's new Special Vehicle Operations (SVO) division, took on the task of researching the original Lightweight E-Types and developing the methods to create new ones. Every aspect of the continuation Lightweight E-Type, from the development of the tools and molds used to build the cars, to the hand-craftsmanship, reflects doing things the hard way. They may not build them like they used to, but with these six special E-Types, Jaguar comes awfuly close, if not better. Working alongside the design team, Jaguar Heritage made a CAD scan of one side of an original Lightweight E-Type body. That scan was flipped to create a full car's worth of measurements. That ensured greater symmetry and better fit than on the original Lightweight E-Types (which could see five to ten millimeter variance, left-to-right). The scan was also used to perfect the frame, while Jaguar looked through notes in its crash repair books to reverse-engineer the Lightweight E-Type's suspension. The team repurposed a lot of existing tooling for the continuation cars, and developed the rest from analysis of the CAD scan.

2020 Jaguar I-Pace Suspension Deep Dive | All kinds of weird and wonderful

I’ve driven the Jaguar I-Pace a handful of times, and it always proves to be an enjoyable experience. In case youÂ’re not up to speed, this is JaguarÂ’s dual-motor all-wheel drive all-electric SUV. ItÂ’s quick, it looks cool in a running shoe sort of way, and it delivers a decent 234 miles of range. Sure, it has its faults, particularly when it comes to the infotainment and climate control layout. But the electric JagÂ’s smooth ride comfort and direct steering feel are clear strong points, and its handling stays nicely balanced and displays sharp reflexes as far as IÂ’ve pushed it. That is to say, a strong pace, but nothing that would land me in jail. The suspension plays a big role in all of this, of course. I wanted to see what theyÂ’d done, so I recently put an I-Pace HSE up on jackstands and took a look underneath. Electric powertrain notwithstanding, I found this to be an utterly weird and fascinating machine.    From this vantage it is easy to see the big air spring (yellow arrow). The use of this type of spring medium allows the I-Pace to run at different heights. It mostly runs at standard height, but can also lower the car at highway speeds to lessen aerodynamic drag. ThereÂ’s an even lower mode to ease the loading of passengers and cargo, along with a raised-height off-road mode because, well, this is theoretically an SUV. It looks like it has a double wishbone front suspension, too, with a high-mount upper arm (green). But we canÂ’t be sure until we move in closer.   With the wheel turned, we can see that this is a double wishbone front suspension in the sense that it has a single ball joint (green) at the bottom. ThereÂ’s lots of nice-looking forged and hollow-cast aluminum bits and pieces, too. But it looks odd in some other respects. The lower arm (yellow), for example, seems to have a joint of some kind in it. Meanwhile, near the top, you can see how the tall upright (or hub carrier, if you like) is curved (red) to provide tire and wheel clearance. Use the wheel studs as a reference point and you can imagine how the tire assembly will nestle into that area.   The shock absorber (green) runs up the middle of what is a doughnut-shaped air chamber. A very tall tower of a doughnut, but you get the idea. But you canÂ’t call this a coil-over. Do I hear bag-over? Anyway, a position sensor (yellow) is connected to the upper arm so the height-control system can regulate itself properly.

Jaguar Land Rover and Cambridge have developed a touchless touchscreen

Jaguar Land Rover and the University of Cambridge are working on new touchscreen technology that eliminates the need to touch the screen. Counterintuitive, right? It’s called “predictive touch” for now, in part because the system is able to predict what you might be aiming for on the screen.  The video at the top of this post is the best way to understand how users will interact with the tech, but weÂ’ll do some more explaining here. You simply reach out with your finger pointing toward the item on screen that you want to select. ItÂ’ll highlight the item and then select it. HereÂ’s how it works, according to the University of Cambridge: “The technology uses machine intelligence to determine the item the user intends to select on the screen early in the pointing task, speeding up the interaction. It uses a gesture tracker, including vision-based or radio frequency-based sensors, which are increasingly common in consumer electronics; contextual information such as user profile, interface design, environmental conditions; and data available from other sensors, such as an eye-gaze tracker, to infer the userÂ’s intent in real time.” Cambridge claims that lab tests showed a 50 percent reduction in both effort and time by the driver in using the screen, which would theoretically translate to more time looking at the road and less time jabbing away at the screen. If the prediction and machine learning tech is good enough, we could see this resulting in a reduced number of accidental inputs. However, on a certain level it almost sounds more difficult to point at a screen while moving than it does to actually touch a section of that screen. Without using the tech and its supposedly great predictive abilities, we canÂ’t come to any grand conclusions. One comparison you may already be thinking of is BMWÂ’s Gesture Controls. ItÂ’s already been addressed with a subtle diss from Cambridge: “Our technology has numerous advantages over more basic mid-air interaction techniques or conventional gesture recognition, because it supports intuitive interactions with legacy interface designs and doesnÂ’t require any learning on the part of the user,” said Dr Bashar Ahmad of the University of Cambridge. Of course, this tech can be used for much more than just vehicle touchscreen control. Cambridge says it could be integrated into ATMs, airport check-in kiosks, grocery store self checkouts and more.
