博塔斯：凯迪拉克解决刹车过热问题，温度降低100度
博塔斯公布了一个数字，展示凯迪拉克的刹车散热修复方案在经历可靠性问题后有多么关键。
瓦尔特利·博塔斯透露，凯迪拉克已将其前刹车温度降低了100摄氏度，治愈了这支新组建F1车队的阿喀琉斯之踵。
刹车过热一直是MAC-26赛车的重大问题，迫使博塔斯在匈牙利、摩纳哥和奥地利三站退赛，这一问题还导致塞尔吉奥·佩雷斯在红牛环的正赛中退赛。
除此之外，过热问题意味着凯迪拉克的车手在最近的西班牙大奖赛全程都必须小心翼翼地应对这一毛病。
车队在亨格罗林更新了进气口和开口表面，这对缓解问题收效甚微，但在阿塞拜疆大奖赛引入的升级版冷却进气和排气管道轮廓则更为成功。
当Motorsport.com问及这一修复方案的效果时，博塔斯回答：“不错，根据之前规格的数据，我们降低了大约100度的刹车温度，所以这确实给了我们更多余量。”炎热的雪邦赛道可能成为本周末的一块试金石。
与此同时，佩雷斯表示法拉利的ADUO 2动力单元升级只值“大约0.15秒”。
“虽然不完全是我们需要的跨越，但每一点进步都有意义，”他补充道。
也许凯迪拉克的新成员会为明年的更大进步做出贡献。上周末，车队宣布了三项工程领域的签约——前红牛首席设计师克雷格·斯金纳、前阿斯顿·马丁技术副总监埃里克·布兰丁，以及曾在迈凯伦、红牛和法拉利等顶级车队工作过的空气动力学家蒂姆·利恩。
斯金纳现在担任凯迪拉克的首席研发工程师，布兰丁成为其空气动力学主管，利恩则以空气动力学建模与仿真首席工程师的身份加入。
“车队正在展现他们对一级方程式的认真态度和投入程度，”佩雷斯评论道。“这些是很棒的引援，他们都是真正会推动我们车队前进的人。别忘了这只是我们的第一个赛季，所以这辆车非常基础，因此我对明年寄予厚望，我们一定会向前迈进。”
“我和克雷格共事过，他在红牛体系里非常出色，在那里他十分重要。
“实际上他在我的赛车地板上做出了很大改变；我记得在巴库那站之前，我们一直为弯道入口的稳定性发愁，他设计出一种加装在地板上的垫块，彻底改变了我的平衡和我的赛车。遗憾的是，比赛后因为卡洛斯（塞恩斯）的撞车，那块地板被毁掉了，我再也没能继续使用它，但那确实是很大的一步。所以他是个非常厉害的人，而且明白我的需求是什么。”
与此同时，佩雷斯认为，鉴于雪邦赛道的大弯角特性，凯迪拉克在马来西亚举行的巴林大奖赛上（原文如此）将很可能陷入苦战。
“我可不期待马来西亚，”他说。“我想我们会回到自己的真实水平。”

Cadillac fix cooled F1 brakes by 100C – Valtteri Bottas
Bottas reveals a figure that shows how crucial Cadillac’s brake cooling fix is, following reliability trouble
Cadillac has reduced its front brake temperature by 100C, Valtteri Bottas has revealed, curing one of the nascent Formula 1 team’s Achilles’ heels.
Brake overheating has been a major issue with the MAC-26, forcing Bottas into retirement in Hungary, Monaco and Austria, with the problem also taking Sergio Perez out of the Red Bull Ring race.
On top of this, the overheating meant Cadillac drivers had to nurse the issue throughout the recent Spanish Grand Prix.
The squad updated its inlet scoop and aperture surfaces at the Hungaroring, which did little to alleviate the problem, but the upgraded cooling inlet and exit duct profiles introduced at the Azerbaijan GP have been more successful.
When asked by Motorsport.com how the fix was working, Bottas replied: “Good, we've reduced about 100 degrees of brake temperature, based on numbers from the previous spec, so that gives us more margin, for sure.” The hot Sepang circuit could now be a litmus test this weekend.
Meanwhile, Perez described Ferrari’s ADUO 2 power unit upgrade as being worth “just a tenth and a half”.
“Not quite the step we needed, but everything counts,” he added.
Perhaps Cadillac’s new recruits will contribute to bigger steps for next year. Last weekend, the team announced three signings in the engineering field – former Red Bull chief designer Craig Skinner, former Aston Martin deputy tech chief Eric Blandin, and aerodynamicist Tim Lean, who has worked at top teams McLaren, Red Bull and Ferrari.
Skinner is now Cadillac’s chief development engineer, Blandin has become its head of aerodynamics, and Lean has joined as chief engineer for aerodynamics modelling and simulation.
“The team is showing how serious they are and how committed they are into Formula 1,” Perez commented. “They are great hires, they are people that are really going to push our team forward. Don't forget that it's just our first season, so this car is very basic, so I have a big hope on next year that we will definitely be moving forward.
“With Craig I've worked and he was really good in the Red Bull organisation, he was very important there.
“Actually he made a very big difference with my floor; I remember coming into Baku when we were struggling with the entry stability, he figured out a packer into the floor, and it transformed my balance and my car. Unfortunately the floor was destroyed after the race with the crash of Carlos [Sainz], and I never got to race it again, but it was a really good step, so he's someone that is really good and understands what are my needs.”
In the meantime, Perez very much expects Cadillac to struggle at the Bahrain Grand Prix in Malaysia, based on Sepang’s sweeping corners.
“I'm not looking forward to Malaysia,” he said. “I think we will be back to our reality.”
