Every Bugatti goes through endurance and high-speed testing while it is being developed, but aside from that, Bugatti also ensures that the cars also go through extreme heat and cold tests. This is true for every Bugatti model, even the few-offs like the Bugatti Centodieci.

For several days, the Centodieci was parked in the special climate chamber. The engineers conducted tests on the model at room temperature. They also ran some heat tests with the car at up to 50 degrees Celsius. Bugatti engineers then went to the other end of the spectrum and are now conducting tests on the car at sub-zero temperatures. For around half a day, the Centodieci was kept at sub-zero temperatures. It might seem to subject the hyper cars to such extreme measures, but the engineers want to ensure that even the tiniest titanium screw as well as the very last carbon part to reach a specified temperature and still work.

Bugatti engineers spend around a week in the climate chamber, testing the upcoming Centodieci and checking every component and parts while inside. The Technical Project Manager for one-off and few-off projects at Bugatti, Carl Heilenkötter shared, “Like any other Bugatti, the Centodieci has to perform impeccably at all temperatures, be it 50 degrees Celsius or minus 20 degrees Celsius. We owe this to our quality pledge and to our customers. With the climate chamber, we can replicate all kinds of different tests and precisely compare the results again and again.”

The tests done in the climate chamber – exposing the Centodieci to extreme heat and cold – is vital as it is the only way for the engineers to ensure that the Centodieci will function safely at all times in all conditions, even if technically, the client will not expose their vehicles to such extreme climate conditions.

A multitude of tests are done on the Centodieci during these climate tests. One of them is the cold test on the side windows. To measure the side window excessive force limitation, even a small production run of ten cars will still have to ensure that internal standards and legal requirements are met and complied with. Bugatti electrics/electronics development engineer Jülf Fiedler explained, “A side window has to recognize a defined resistance level and its raising be reversed if necessary.”

The software used on the side window motor have a set of predefined parameters to regulate the power that is needed to ensure a seamless operation. It also protects people through a stop/reversing function. If they didn’t identify resistance, the window can easily slice an apple, or even crush a person’s finger.

The side windows are raised and lowered hundreds of times and they determine the force using a measuring instrument. Everything has to be precisely coordinated, from the motor power to the seal resistance, friction, and the reversing gear and glass. If any changes are made on the seal material, window size, or the drive, they repeat the tests as the seal plastic behaves differently in different set-ups. Fiedler added, “The seal friction varies depending on the temperature, and this has to be taken into account by the software for the side window motor. The side windows have to rise reliably whatever the temperature and

Here comes trouble: A Triumph TR6 with a Matchless frame

custom triumph tr6 matchless frame 625x417 1

Kids are impressionable, especially when motorcycles are involved. That magical combination of sound, smell and danger has a way of imprinting itself on young minds. But Kyle Harvey didn’t just dream of bikes as a child—he practically grew up with them.

Kyle’s trade is tool and die making, but his passion is building bikes. His father, Garth Harvey, got Kyle and his brother into bikes at a young age; as soon as they could start their old man’s vintage motorcycles, they were riding them. Living in Edenvale in South Africa’s Gauteng province, the boys also had direct access to the local Classic Motorcycle Club.

 

The folks at the CMC made quite an impression on young Kyle—and taught him everything he knows about vintage bikes. After helping numerous friends work on their bikes, he went on to open his own shop, named simply ‘The Workshop.’ Kyle has been building and restoring classic motorcycles for over a decade now.

This cheeky bobber is his latest build, and it’s immensely fascinating. The engine’s from a Triumph TR6 Trophy, the frame is from a Matchless, and the quirky handmade details on it are endless.

The Swan Song of the V12

Published

on

The V12 engine holds a special place in the heart of many automotive and motorsports fans. For some, it’s the sound of Formula 1 through the years, especially during the 1990s. For others, it’s engines like the 6.1 L BMW S70/2 from the McLaren F1 or the 3.9L Lamborghini V12 that powered all their cars from the Miura through to the Diablo. No matter where it lies in your heart, it is the “proper” configuration for many: 6 cylinders per bank, put into a V, and firing in an odd sequence to give it that special roar under power.

Yet, as concerns over fuel efficiency, qualms about environmental impact, and high-powered turbocharged V8 or V6 engines are the norm now, the V12 is slowly, but surely, being put to rest. In fact, the only place that V12s are still hanging on by the last threads of their engine mounting bolts are in supercars, hypercars, and a few ultra-luxury cars. Even then, many exotic brands have announced that their next cars will either be V10s or turbo V8s and V6s.

Since it appears that the swan song of the V12 is reaching a crescendo, we thought it only appropriate to celebrate the few remaining cars out there that carry them. It may be the last time we see some of these brands, many of which are known for their V12s.

The writing is on the wall for the prancing horse, as the new Ferrari 296 GTB is showing the direction that Maranello is headed. Yet, unless you were invited to snag one of the limited-edition Monza SP1 or SP2 cars, there is still one car you can buy from the legendary marque that has all 12 cylinders fully intact.

The 6.5L F140 GA 65-degree V12 in the front of the 812 is the last road-going version of the V12 that debuted in the Ferrari Enzo. Producing a monstrous 789 HP and 530 lbs-ft of torque, it is no slouch either, as when the 812 Superfast debuted, it was the most powerful naturally aspirated production car engine ever made.

It has the typical low-rev Ferrari roar that rises into a howl as the car revs up to nearly 9,000 RPM, and will catapult the 3,845 (1,744 kg) car to 60 MPH in 2.9 seconds. As far as a curtain call is concerned, that’s a great way to bow out and focus on hybrids and turbocharged engines.

Mercedes-Benz used to be at the very top of the V12 pecking order when it came to luxury performance cars. Such classics as the S 65 AMG from the mid-2000s and the 500 TE AMG W123 Touring from the very end of the 1970s came with big V12s that sound astounding, but the biggest and baddest of the Mercedes V12s left on in a production car is the M279 E60 LA that hauled the S65 AMGs of 2014.

Road Tested: Gear from Shoei, Akin Moto and Rev’It!

Published

on

In our continuing quest to source motorcycle gear that combines safety and style, we bring you our thoughts on Shoei’s new ECE 22.06-approved NXR2 helmet. Plus a stealthy riding parka from Akin Moto, and the perfect pair of urban riding gloves from Rev’It!.

Shoei NXR2 helmet It’s no secret that I’m a huge fan of Shoei’s helmets. Every Shoei I’ve owned has fit and felt right from the first wear, with no major deviations in their sizing or shape from model to model. So when I was looking for a do-it-all street helmet to replace my well-used Shoei RYD, the new NXR2 was a no-brainer… and it hasn’t disappointed.

I loved the RYD for its combination of neutral styling, comfort and ventilation. The NXR2 basically feels like a premium version of the RYD; it has the same clean aesthetic, but ramps up the performance. And it’s one of the few helmets that meet with Europe’s new, and more stringent, ECE 22.06 standard.
