The disc brake is a key example of trickle-down technology in the automotive industry. One that starts at the highest forms of motorsports, and eventually makes its way down to the masses. In the case of disc brakes, it completely revolutionized the way we view cars and driving. OUTRUN seems to think so too, as they’ve produced a stunning documentary on the disc brake’s origin titled The Racers that Stopped the World.

The documentary follows the story of legendary racing driver Sir Stirling Moss and famed Jaguar test driver and engineer Norman Dewis as they were involved with the development of the disc brake. Other notable figures of motorsport in the documentary include Murray Walker, Sir Jackie Stewart, Martin Brundle, Derek Bell, and Andrew Frankel, who recount their personal experiences and insights on the story.

With Moss already on his way to becoming one of the greatest racing drivers in history, he took a look at a new brake concept that Norman Dewis had been working on alongside Jaguar and Dunlop’s engineering teams. They were looking to completely revolutionize the concept of braking, as it wasn’t able to keep up with how quick the cars of the time were becoming.

They had taken inspiration from Dunlop’s airplane division, which at the time, was starting to toy with the idea of disc brakes. The idea was to use pads clamping down on a rotor instead of pushing out on a drum, with the goal of creating more powerful, consistent brakes that were also more resistant to fade.

Though both disc and drum brakes relied on the same basic principles (friction and heat) to slow a vehicle down, the disk brake’s design was far superior to that of the drum. Since drum brakes were enclosed, heat builds up much quicker, while since disk brakes were fully exposed to the outside air, so they allowed for monumentally better cooling. That in turn reduced fade and made for more consistent braking.

The concept itself was quite quite simple, a real example of “Why hasn’t someone done this before?”. However, as it turned out, while the general idea might’ve seemed simple, the hardest part was actually getting it to work and perfecting it to perform reliably.

They decided to test their concept at the Mille Miglia, figuring all the hard braking on the winding mountainous roads would surely put the new tech through its paces. And they were right, as it helped them greatly during the race. The disc brakes allowed the driver to carry their speed much further into a corner, as well as apply greater braking force as late as possible without worrying about overheating. Eventually, they perfected their technology, and as is with so many other automotive advances, it eventually found its way to the cars driven by everyday people on public roads.

Filmed around eight years ago but never released, when Sir Stirling Moss passed away in April 2020, the producers of the documentary decided to take the original footage they’d shot and start again to create this film, and eventually they were able to release this brand new reworking of the project so that the story can be told.

Even luxury brands are not impervious to the trend for greener vehicles, not to mention ever-tightening emission regulations. One such example is the 2021 Range Rover, which is available with a plug-in hybrid 2.0-liter four-cylinder powertrain.

We must admit that the idea of a 2.0-liter four-cylinder engine under the bonnet of the Range Rover, even when aided by a plug-in hybrid system, still sounds a bit weird, but apparently, Land Rover did a great job on this occasion.

Carwow reviewed the latest 2021 Range Rover P400e to find out if this electrified variant is still capable of impressing new and old customers alike.

The plug-in hybrid version of the 2021 Range Rover offers a combined, and very respectable, 398 HP (404 PS) and 472 lb-ft (640 Nm) of torque by pairing a 295 HP 2.0-liter petrol with a 141 HP electric motor and a 13.1 kWh battery pack.

0-62 mph (100 km/h) comes in 6.4 seconds, while Land Rover claims a pure EV range of up to 25 miles (40 km), CO2 emissions of just 75g/km, and a fuel economy of up to 84.8 mpg UK (3.3 lt/100km / 70.61 mpg US) on the WLTP combined cycle.

2021 is also a landmark year for the Range Rover, as the model celebrates its 50th anniversary. To mark the occasion, Land Rover also offers a limited 50th Anniversary Fifty edition, as well as three new special editions: Westminster, Westminster Black, and SVAutobiography Black.

While the plug-in hybrid powertrain isn’t the smoothest in combining the power from its two power sources, it manages to move the 2.5-tonne SUV quite swiftly and offers enough electric juice to cover short distances within city limits with zero emissions.

In addition, the Range Rover retains the plush ride quality and an expensive atmosphere in its cabin, two factors that played a crucial role in gaining so many customers over the years. Sure, new models may look more modern -and sportier- at places, but the Range Rover remains a classic status symbol.

At least until the new-generation Range Rover arrives, which shouldn’t be far away.


去年美國車廠 SSC(Shelby SuperCars)宣布,旗下超跑 Tuatara 創下最速量產車紀錄,但由於缺少具公信力的第三方認證,真實性遭到質疑,近日該車廠再度進行測試,再度認證其最速量產車身分,並獲得金氏世界紀錄認證。

當時 SSC 公布自家超跑 Tuatara 的極速紀錄時,遭質疑測量儀器不合規範,並且缺少具公信力的第三方認證,時隔兩個月,SSC 再度挑戰紀錄,並找來完整認證團隊,在美國佛羅里達州甘迺迪太空中心的 NASA 飛機跑道上完成測試。

美國車廠 SSC 超跑 Tuatara 確認奪下最速量產車頭銜,並獲金氏世界紀錄認證。

根據金氏世界紀錄的規定,挑戰車款需要具備一定產量,符合量產車身分,並在 1 小時內於同一段道路來回各衝刺一趟,取兩趟的平均值作為最終成績,而此次 Tuatara 第一趟跑出 450.1km/h 極速、第二趟則為 460.4km/h,平均達 455.3km/h。

雖然這次的成績與先前 SSC 公布的 508.73km/h 有落差,原廠表示,這是因為跑道長度不夠。不過 455.3km/h 最高極速的成績也已經足夠讓 Tuatara 奪下全球最速量產車的寶座,成功擠下 Koenigsegg Agera RS 所創下的 447.2km/h 紀錄。

SSC Tuatara 搭載 5.9 升雙渦輪 V8 引擎,售價從 162.5 萬美元起(約 4700 萬元台幣)起跳。

這款 SSC Tuatara 搭載 5.9 升雙渦輪 V8 引擎,最大馬力高達 1350hp,產量為 100 輛,售價也從 162.5 萬美元起(約 4700 萬元台幣),若是配備 High Downforce Track Pack 的車型,售價更高達 190 萬美元(約 5500 萬元台幣)。
