The racetrack is the ultimate stage for new motorsports technology and innovations. Our advanced products go to work in race cars to help improve their performance and efficiency. Motorsports defines us. It’s integral to how we develop technologies and constantly push the boundaries.
As a technology partner of McLaren-Honda, a team competing for race wins and championships, Mobil 1 scientists are under constant pressure to come up with new ideas. Racing is all about improving at a very rapid pace – the team is looking for an improvement every two weeks. Even tiny upgrades can make the difference between winning and not. The secret is the ability to innovate and adapt.
“Hold on tight!” Get an exclusive “ride” inside a high-performance Grand Prix engine to see how Mobil 1™ synthetic motor oil provides optimum engine efficiency benefits for Formula 1® world champions Fernando Alonso and Jenson Button.
Engine technology: Running like new
Bruce W. Crawley is one of ExxonMobil’s foremost technical experts, having joined the company in 1982. He leads a team of scientists and trackside engineers who develop innovative products and support motorsports partnerships in multiple categories around the world.
As the technology demands of Grand Prix racing have changed, the Mobil 1 team has rapidly and successfully evolved its products to remain at the forefront of competition, just as the cars adapt continuously through each season. In 2015, with drivers only allowed four engines per season, a new Mobil 1 engine oil was developed for the Honda RA615H engine to keep the engine clean and help minimize friction and wear.
Longevity and performance are vital in Grand Prix racing, with each engine expected to cover thousands of miles while making more power from a smaller displacement. The lubricants must help keep the engine’s internal surfaces clean and free from deposit buildup, and they also prevent wear.
Hydraulic system technology: Fluid thinking
The hydraulic system is vital in nearly all aspects of a Grand Prix car’s performance. The hydraulics control gear shifting, throttle actuation,
differential locking, the clutch and the DRS (drag reduction system). They even control the steering system that is essential to the functionality of the
car. Simply put, hydraulics are the nervous system of the car. Above all else, they need to be 100 percent reliable.
Mobilith SHC™ ensures that the hydraulic oil in a Grand Prix car is capable of delivering optimum performance and is designed to operate at an incredible
200 bar, withstanding temperatures of over 100 degrees Celsius (212 Fahrenheit). Just like engine and gearbox oil, hydraulic oil needs to run blisteringly hot with
as little fluid as possible so that efficiencies can be achieved.
To deliver maximum performance at every Grand Prix, Mobil 1 engineers continuously run a rigid program of sampling and analysis of the product, ensuring
its performance capability. Hydraulic oil and the hydraulic system are vital to the operation of a Grand Prix car. If these systems are not functioning
correctly the car will stop.
Gearbox technology: Gear lubrication
The gearbox is extremely important to achieving success, as it is what delivers the car’s power from the engine to the wheels. Part of the challenge
for the gearbox designer and the oil engineers is making sure that the gears in the gearbox are protected and well lubricated, and that the heat is managed
Mobil 1 gearbox oil is unique in that it helps protect the gearbox and maximizes efficiency, ensuring nearly all of an engine’s power can be translated
into speed on the track. Because of this, Mobilube 1 SHC™ Racing Gear oil is one of the top-secret performance aids for some of the world’s best race teams.
For example, a Grand Prix gearbox is one of the most extreme environments in which lubricating oil is expected to function. It is battered by vibration and
subjected to high temperatures, furiously quick rotational speeds and vicious g-loadings. The contact pressures between the gears can be measured in
gigapascals at levels similar to those occurring in tectonic plate movement that causes earthquakes, which is enough pressure to physically deform steel.
These extreme conditions make it the perfect test bed for new ideas and an exciting challenge to develop new products.
Mobil 1 provides high-performance lubricant products for many motorsport teams around the world. In addition to this, we also provide trackside
support from our expert engineers, which helps to improve reliability and reduce the risk of cars not finishing races.
Mike Frost, one of our racing engineers, is present at every Grand Prix race, and is a key member of the McLaren-Honda team. The ExxonMobil Analytical Center he
uses provides the team with near real-time information on the health and condition of the engine, gearbox and hydraulics. This trackside laboratory comprises of a spark
emissions spectrometer, which is used to measure the particles in the engine oil, the gear oil and the hydraulic oil. When the car comes back into the
garage after every track session, a sample of the engine oil is taken and tested on the spot, helping to diagnose problems early.
The oil analysis testing can detect a very fine distribution of wear metals and contaminants, including lead, indium, copper, tin and iron, which can be as
small as one-tenth the width of a human hair. Within a matter of minutes, the samples are taken, analysis is made and we are able to report to the team
with information to diagnose a problem such as a bearing breaking down or excessive gear wear. It gives the team a chance to put a defensive strategy in
place to avoid the severe penalties for changing engines or gearboxes during a race weekend and increases the reliability of the car’s ability to finish
Performance gains in motorsports are made through the improvement of every single aspect of a race car. Our job is to help get as much power, as
efficiently as possible, from the engine out through the drivetrain and to the wheels. Some of the more hidden elements of wheel technology contribute to
improving lap speed, and wheel bearings are an important, sometimes overlooked, component.
With the tires, the teams are looking for as much friction as possible to generate more traction. Wheel bearings work completely opposite to the tires in
that the friction needs to be reduced as much as possible in order to maximize speed.
In NASCAR®, wheel bearings are expected to cope with extreme loads, perform hundreds of thousands of revolutions flawlessly and operate at high
temperatures. Mobilith SHC grease allows the wheel bearings to operate effectively in these extreme conditions, translating the power more efficiently to
the wheels. It also helps minimize the required brake ducting needed to cool the wheel hub. Less ducting produces a more streamlined car, meaning more down
force. Ultimately, better wheel bearing lubrication translates to improved lap time.
