Lola B08/80
Finding one's niche makes all the difference in the world. Whether searching for a career or offering a product, finding out what one is good at will make the difference between failure and success.
In the case of Lola, finding their niche saved the company. Despite over fifty years of experience, the company nearly lost it all when it entered the ever-changing, and incredibly expensive, world of Formula One. The mindset of Lola was in sharp contrast to the mindset required to be victorious in Formula One. Saved from utter failure and ruin, the company stepped-back and focused on what they were good at.
One of the biggest markets for Lola has come in the form of Le Mans endurance racing. Given the regulations and the wide-range of competitors, Lola has found its niche in the LMP1 and LMP2 categories.
Because Le Mans and Le Mans Series racing are still the only series in which amateur drivers are still allowed to take part, there are many smaller-budgeted teams throughout the world looking to compete. This suits Lola perfectly. By designing, building and providing everything else necessary 'in-house', Lola offers racing teams an affordable means in which to go race, and do so competitively.
Lola launched its first LMP prototype model, the B05/40 in 2005. Each and every year, the company has built upon its experience to provide teams with competitive chassis. The chassis faced stiff competition in the LMP1 category as the customer Lola cars faced purposed-built prototypes like the Audi R8. However, in the LMP2 category, Lola has found immediate success. One of the biggest reasons for its success has been due, in no small part, to its ability to still customize its cars for its particular customer's needs, especially with the ability to house any number of engine possibilities under its car's bodywork.
In its pursuit to provide customers with the most competitive chassis possible, Lola launched their new Lola B08/80 in 2008. Debuted in tandem with the larger and heavier Lola B08/60 for the LMP1 class, the B08/80 promises to offer the company greater chances of success. While the B08/60, which was a customer-based design, would have to face the might of the purpose-built Audi and Peugeot with their diesel-powered cars, the B08/80 was believed to help Lola set the pace in LMP2. Benefiting from the same design as that used on the B08/60, the shorter and lighter version was intended to be able to take the fight to the Porsche Spyders which had been dominate throughout 2006 and 2007.
Starting from features of previous chassis that worked, Lola set to work building an even better LMP2 competitor. What resulted when they were done was a car that would offer teams wholly new possibilities.
Lola took what worked from its latest LMP chassis, the B07, which included aspects like the car's nose design, and combined that with research using Computational Fluid Dynamics software and testing in the windtunnel to create its latest generation prototype challenger.
Each of the B08/80's front wheel fairings feature the upward sweeping design just like on the B07. It features the fairing pulling in at the bottom of each side to form a 'V' shape. This allows greater flow of air between the front wheel fairings and the nose bulkhead bodywork. By pulling in the bodywork of the fairing from the outside a flared design is created by the bodywork to cover the outside edge of the wheels as fitting with the regulations. What this design also allows; however, is space. This space enables teams to use varying numbers and sizes of small wing elements to help control the downforce and stability of the car, especially at the front.
The headlight arrangement with the leading edge of the front wheel fairing remains untouched. Though teams may opt to run varying headlight combinations, the headlights were designed to sit horizontally in the very narrow fairing leading edge instead of vertically.
As per the regulations, the leading edge of the front diffuser/splitter, features the step-up in its design. This move reduces overall downforce at the front of the car as it allows more volume of air. Being squeezed between the diffuser and the ground, the air speeds up creating a lower pressure, which creates lift in the opposite direction, downward.
Though a design element on the Lola for a couple of years, the raised-nose on the B07 followed the lead of the Porsche Spyder and was changed. The B08 utilizes the same design. Though the very front edge of the nose remains raised like the B07, the B08's nose bulkhead also has grown vertically. This creates a deeper channel for airflow between the front wheel fairings and the nose. But it also helps in other ways. On the B07, the top of the bodywork's design line featured a number of bulges and bumps to cover suspension members and other components. However, the top design line of the B08 is more-rounded, but smooth. Every aspect of the suspension, and other components, remains hidden under the bodywork.
One of the important design aspects that had to be considered, and was designed into the B08/80, was the ability to be flexible concerning suspension arrangements and geometries. As a result, the B08/80 was designed with a number of attachment points for suspension, which allows teams to choose their own suspension types and arrangements, while not having to build a whole-new car around those decisions.
One more important element somewhat masked in the raised nose of the B08/80 were the inlets for the cooling of the massive carbon brakes. The ram air would enter the individual openings hidden in the nose and travel to each brake housing to help cool the brakes.
The top of the front wheel fairing is another area of vital importance to any prototype endurance car. Multiple styles of panels can be attached to the top of the front wheel fairings to help with overall grip levels at the front of the car. Should the track be a low-downforce, or fast, track a smooth panel may be attached to the top. This reduces drag and helps increase top-end speed. However, a panel with a number of tall louvers may also be attached to the top. These louvers help to create a suctioning effect of the air built-up around the front tires. As the air passes over the louvers and sucks the air within the wheel-well out, it pushes the car down to the track increasing downforce.
Much of the Lola B08/80's performance is the result of what the air is doing underneath the car. As it enters the front it gets squeezed by the contoured front diffuer/splitter. This creates a vast amount of the downforce at the front of the car. The splitter then stops and the air can head back toward the radiator sidepods, and also out the side of the car.
Just aft of the front wheel fairings comes the biggest difference between the Lola B08/80 and any of Lola's previous prototype designs. The Lola designer Julian Sole created a coupe design for the B08/80. This meant Lola offered the first closed-cockpit design in the LMP2 category, which offered customers more options to choose from.
Quite tight, the closed-cockpit design amazingly conforms to the ACO regulations concerning the car being a two-seater. While perhaps appearing to be absolutely impossible to pull-off, the template for the two-seater did manage to fit inside the cockpit. Access to the cockpit comes in the form of a recessed portion of the coupe's roof that allows a hand to reach in and pull open the door. The door hinges forward and upward slightly.
Inside the tight cockpit, Lola has provided its customers many choices once again. Able to be done 'in-house', Lola has the capability to run a number of different electronics packages throughout the chassis and in the cockpit. The cockpit utilizes the ACO-mandated air-conditioning system and features adjustable pedals and steering column for any type of driver. Drawing from its military contracts, Lola integrated the wiring loops and redundancy systems right into the monocoque structure for reliability, access and ultimate crash protection.
Teams can incorporate a number of systems with the chassis as well. A number of pneumatic or solenoid automated steering wheel-mounted paddle-shifting systems can be used and are easily adaptable to Lola's own HT gearbox. Lola designed the car, and is itself, more than capable of integrating practically any data system, telemetry or cockpit display a team would desire into the car. One important, not often thought about feature the Lola B08/80 included was the addition of electrically operated moveable rear-view mirrors. The cockpit itself was created as part of a single carbon monocoque survival cell.
View out of the closed-cockpit is very restricted due to the carbon-monocoque structure of the cockpit. Even vision out the side of the car is hindered because of the design of the closed-cockpit.
Following in similar fashion to its B07, the B08/80 featured squared-off front wheel fairing extensions. Designed in conjunction with the radiator sidepods, the extended bodywork helps to blend the air flowing toward the sidepod to flow around it and over the top of the car. By reducing the airflow colliding with other airflow, disturbances are reduced, which reduces instability and drag.
The sidepods; themselves, are tall vertically and run right up to the bottom-edge of the door, but are pulled in drastically from the side. This allows any unneeded air to pass around the side of the car and blend into the air passing by the car.
The line of the sidepod gently sweeps downward as it travels aft. It then integrates with the leading edge of the rear wheel fairing. Incorporated into the leading edge of the rear wheel fairing can be either simple slot openings, or, scoops to collect air to help cool the carbon rear brakes. The sides of the sidepod bodywork have been designed to feature a couple of different design options. Large shutters can be incorporated to use airflow passing along the side of the car to pull the heat built up in the radiator out the side of the car, or, an actual slot design can be used to do the same function. One design pulls the hotter air out the side of the car, while the other pulls it inward and out the back of the car.
Since the B08/80 had been designed as a customer car, a number of engine arrangements and types are easily housed underneath the car's rear bodywork. In the case of a turbocharged engine used by a team, a larger, single air-scoop will protrude out of the top of the left sidepod. Should a normally-aspirated engine be the choice of a team, the air-restrictor is positioned in streamlined bodywork that runs along the top of the cockpit. In addition to the turbocharger air-scoop protruding out of the top of the bodywork, the exhausts also protrude out of the top of the rear deck of the bodywork. Dependent upon the type of engine used, one or two exhausts will protrude out of the top of the bodywork shrouded by a contoured housing to help reduce airflow disruption in the area.
The trailing edge of the rear bodywork has been designed to allow for another small aid in adding downforce to the rear of the car. A small vertical flap can either be added or taken away from the trailing edge depending upon the needed downforce levels for a particular track.
Besides the trailing edge of the rear bodywork between the rear wheel fairings, the rear wheel fairings themselves were designed with neat little wing elements designed into them to use the air flowing over the fairing to help generate just a little more downforce before it leaves out the back of the car. And, as with the front wheel fairings, different types of panels can be attached to the top of the fairing to help with downforce at the rear of the car.
Talking about downforce, and the rear of the car, perhaps one of the most important elements for a fast prototype racer would be the rear wing. In the case of the B08/80, Lola designed a straight-forward rear wing. Supported by twin-pillars, the B08/08 uses a conventional wing, void of contours and many other design elements one may be used to from looking at a Formula One rear wing. However, the design utilizes a twin-plane design and endplates that serve another purpose.
The endplates aren't merely used anymore to help attach the rear wing plane elements and hold them firm. Designers, like that at Lola, have been using the endplates to help with stability at the rear of the car. Though not as much a focus on the Lola B08 as on other car designs, the endplates help to direct the flow of air as it passes out the back of the car. Instead of the air tumbling off out the sides of the car and causing some instability, the endplates help control the flow and help maintain some stability at the back of the car.
Given its adaptability and aerodynamic competitiveness, Lola's B08/80 provides its customers with a highly flexible car and cutting-edge aerodynamics. The Lola B80/80 is an efficient design and a championship-caliber car as well.
