Ayrton Senna was a monster on the track, hitting the apex and flying down the backstretch in ways that made crowds the world over fall in love with his capability. The McLaren Senna, a track-horned road car was designed in the spirit of Senna, the man.

The next-level variant of the McLaren, the Senna GTR, takes that athleticism a step further with a car, "designed to deliver the most extreme, raw and engaging driving experience possible," according to the super luxury automaker. They call the vehicle "mind-bendingly fast", which makes it a perfect fit for a track day.

In the second episode of the McLaren Tech Club series, the company's principle designer Esteban Palazzo discussed the carbon fiber wing on the Senna GTR and why it makes the car so good.

When designing the car, McLaren engineers set out to give the car 1,000 kg (2205 pounds) of downforce at maximum deployment. That's 25 percent more downforce than the traditional Senna. The heralded McLaren P1 offered just 640 kg of downforce at 150 mph.

How did they do it? They substantially reworked the exterior surfaces of the car, giving it a huge front splitter, integrated rear-wing endplates, and a new diffuser. Oh yeah, and that huge wing.

That helps the car stick to the track when it's busy achieving the fastest McLaren lap times outside Formula 1.

The beating heart of the McLaren Senna GTR is a twin-turbocharged 4.0-liter V8 engine that achieves approximately 813 horsepower and 590 pound-feet of torque. Its carbon fiber body weighs just 2619 pounds and rides on a motorsports chassis.

The total engineering package is designed to deliver a raw racing experience. It's beyond engaging. The well-engineered wing helps you ride the line between control and out of control and, quite possibly, life and death.

What does it mean to "drive defined"? A new series of videos from Porsche and the Creative Director of the Paris fashion label Balmain, Olivier Rousteing, explorers the meaning of the phrase. Rousteing says that he's been "fascinated" by Porsche since childhood.

The designer, who grew up in France, worked at Roberto Cavalli before becoming the Creative Director at Balmain in 2011. The powerhouse fashion brand was founded in 1945 and was previously lead by Oscar de la Renta. Modern Balmain designs feature elements of French couture mixed with Asian influence. In 2019, the brand launched the KYLIE X BALMAIN, a makeup collaboration with social media influencer Kylie Jenner.

The short videos, published on Porsche's social media channels and on Rousteing's Instagram feed, focus on Rousteing's powerful inner driving force. In a release, the luxury car manufacturer says that there are "many similarities between the fashion designer and the sports car brand" including boundary pushing and an eye toward the tradition-rich history of the company Rousteing leads into the modern age.

"Olivier Rousteing is not just an authentic Porsche enthusiast, he is also a perfect fit for us with his desire to make Balmain a modern brand with the highest standards of quality and luxury," says Jelena Batic who is responsible for the cooperation at Porsche. "Together, we explore his exceptional driving force in the films by examining the connection between the worlds of sports cars and fashion, which creates relevance for our existing customers, as well as for younger and female target groups."

The series kicked off with a video featuring the Porsche Panamera. It was just the first step in a planned, longer collaboration between Rousteing and Porsche. Further aspects of the partnership are expected to be made public in due course.

McLaren recently shipped its last Sports Series cars to the U.S., marking the end of production of the popular models that have been staples of the luxury carmaker's lineup for the last half-decade. Over 8,500 cars were sold globally.

The Sports Series debuted in 2015 with the 570S, and also included the 540C, 570S Spider, 570GT, 600LT coupe, 600LT Spider, and 620R. The final examples of the series were built at the company's Woking, U.K. headquarters at the end of 2020. The 620R was the last off the line.

The McLaren 620R is a road legal version of a race car. It's based on the McLaren 570S GT4 and uses motorsport technology without the restriction of racing regulations. It is the most powerful Sports Series model ever, with a twin-turbocharged 3.8-liter V8 producing 611 brake horsepower and 457 pound-feet of torque.

The 620R shares aerodynamic hardware with the 570S GT4, creating 408-pounds of downforce at 155 mph. It can handle the road (and you can hear it coming) thanks to its wider track, carbon ceramic brakes and center locking wheels, and low-exit stainless steel sports exhaust.

"As the McLaren range has matured, we've tailored our North American model line-up to closely match customers' requirements, with a car suitable for every personality," explained Tony Joseph, President, McLaren, the Americas. "Limited-numbers models with the highest levels of performance – cars like the 620R, which feels like a race car on the street or at a track day - are in demand not only because of the driving experience they offer but because they have even greater exclusivity. You can see how this has played out with the 765LT as well, with all of the available volume sold."

Of the 225 examples of the 620R produced, only 70 were slated for the North American market. All North American 620R models come with a special MSO upgrade package that features a gloss finish Visual Carbon Fibre roof with a roof scoop to maximize engine intake and exhaust sound, MSO Defined gloss finish carbon fibre roof cantrails and the McLaren Track Telemetry system with lap time function and three cameras to record on-track performance.
