It’s a question that has dominated the history of the XJ13, a prototype built by Jaguar in 1966 in a quest to continue the marque’s legendary run of success in the Le Mans 24 Hours race. Powered by a then-new quad-cam, 5-litre V12, the XJ13 was Jaguar’s first mid-engined car – and without doubt one of the most beautiful automotive designs of all time.
Sadly, it was never raced. A combination of internal politics and a change in sporting regulations meant that it was banished to a corner of the Competition Department – virtually forgotten as other projects took priority.
If the car had been raced…
But what if the XJ13 had been developed and raced? What if this car’s immense potential had been realised? Picture this scene: one day in late 1967, members of Ecurie Ecosse – the famous Scottish race team that twice won Le Mans in the 1950s with Jaguar D-types – travel to the Jaguar factory to discuss repeating that success.
During their visit, they spot the XJ13, covered up and tucked away. But as soon as the covers come off, they know that they’ve got a potential winner on their hands. A deal is done, and work begins on a 2-year project to develop and build a car in order for Ecurie Ecosse to take on the might of Ford, Ferrari and Porsche at the 1969 Le Mans 24 Hours.
This alternate reality could have been one of motor racing’s greatest stories – just imagine if the money, not to say courage and ambition, had been invested into it. Now a team of designers and engineers have done just that…
Birth of the Ecurie Ecosse LM69
50 years on, the LM69 is to be launched and while remaining true in spirit and sympathetic to the style of the XJ13, its bodywork has been developed into an all-new design that has its own purposeful beauty.
The quad-cam V12 is the heart of the car, a unique signature that has been designed to evoke the experience of driving at Le Mans in 1969. And not only is the LM69 suitable for track use, it’s fully road-legal.
Adhering to original design details and technology
A strict brief was established from the start: the design and engineering team would have to adhere to the regulations of the time, and feature only design details and technology that entered motorsport no later than early 1969.
As the XJ13 would have done had it been prepared for serious competition use, the LM69 benefits from innovations that appeared during that exciting era. Composite materials have been used; it’s lighter than the original car, and it boasts experimental aerodynamic devices, wider wheels and tyres, and a much-improved engine.
Only 25 will be handbuilt by British craftsmen, in keeping with the 1969 FIA homologation requirements and to maintain its exclusivity.
TOYOTA GAZOO Racing’s history-making TS050 HYBRID has been further optimised ahead of the 2019-2020 FIA World Endurance Championship (WEC) season as the team prepares to defend its World Championship and Le Mans 24 Hours titles.
The 8-race season, which kicks off this week with the annual Prologue test in Barcelona, Spain, represents the final competitive entry for the TS050 HYBRID. The racing car made its debut in 2016 and has been at the centre of memorable moments in endurance racing history ever since.
Its Le Mans debut almost ended with victory before the unprecedented drama of a technical issue on the penultimate lap. In 2017, Kamui Kobayashi piloted the TS050 HYBRID to the fastest-ever Le Mans lap on his way to pole position, while Mike Conway set a new race record this year.
TS050 HYBRID gave Toyota first-ever Le Mans win
The 2018-2019 WEC season saw the TS050 HYBRID go down in history in 2018 as the first Toyota to win Le Mans, while a repeat 1-2 victory a year later capped an extraordinary season which saw TOYOTA GAZOO Racing win both the Teams’ and Drivers’ World Championships.
For the upcoming season, a 1,000 ps 4-wheel drive hybrid prototype has been modified with revised aerodynamics and further fine-tuning of mechanical parts to strengthen reliability.
“As a team. we have grown stronger and more resilient during the TS050 HYBRID era and we need to demonstrate this again as we challenge to defend our titles and, in parallel, prepare for the new hypercar regulations.”
Hisatake Murata, Team President
Veteran drivers plus newcomers
Behind the wheel of the #7 TS050 HYBRID will continue to be the trio of Mike Conway, Kamui Kobayashi and Jose María Lopez. Brendon Hartley, a former Le Mans winner and WEC champion, joins World Champions Sebastien Buemi and Kazuki Nakajima in the #8 car. Thomas Laurent will combine his new role as test and reserve driver with an LMP2 race seat with Signatech Alpine in order to enhance his development.
The farewell tour for the TS050 HYBRID begins in September with the 4 Hours of Silverstone, the first of 8 races on 4 continents. In total, the car will cover 66 hours of racing on historic tracks such as Sebring, Spa-Francorchamps and Fuji Speedway, ending at Le Mans in mid-June 2020.
Active suspension, as opposed to passive suspension, differs in that the latter – found in the majority of vehicles – is not constantly adjusted to optimise performance on varying surfaces. Passive suspension can be tuned but the settings remain fixed so the engineers often have to find a compromise between handling and comfort.
Active suspension does tuning in real time, with adjustments made as surface conditions change. One could say the hydro-pneumatic concept in Citroen suspension systems from the 1950s onwards was the earliest form of active suspension. Sensors kept track of the road conditions and compression rates of the suspension were varied for comfort and it was also possible to raise and lower the ride height for enhanced stability at higher speeds.
With the electronic age and use of solenoids providing quick actuation, active suspension advanced more quickly in performance. Toyota’s Electronic Modulated Suspension (TEMS) in the Soarer of 1983 is considered the first production example of active suspension using electronics. In the years to follow, more powerful computer processors would alter damping rates in milliseconds as the car moved along at high speed.
Audi’s innovation advances active suspension
Now Audi is offering predictive active suspension for its latest A8 sedan. Depending on the chosen settings, it gives the brand’s flagship model the supreme ride comfort of a chauffeur-driven limousine or the firm handling of a sportscar – no need for compromises. In Germany, this option is priced at 5,450 euros (equivalent to about RM25,000).
A fully active suspension system, it uses electromechanical actuators to adjust the suspension. They can lift up or force down each of the luxury sedan’s wheels individually, to actively manage the body’s ride height in every situation. The active suspension can lift or lower the body by up to 85 mm from its central position at all four corners within 5/10ths of a second.
Compact electric motors are located close to each of the wheels, running off the car’s 48V primary electrical system and governed by power electronics. A belt drive and a compact harmonic drive step up the electric motor’s torque almost 200 times to 1,100 Nm and apply it to a steel rotary tube.
The latter is permanently attached to a preloaded titanium rod located inside it and capable of turning through more than 20 degrees. From the end of the rotary tube, the force is transmitted to the suspension via a lever and coupling rod – at the front suspension, it acts on the spring strut, and at the rear suspension on the transverse link.
Predictive active suspension operates very efficiently. Its average power consumption is in the range of just 10 to 200 watts – much less than that of comparable hydraulic systems. Whenever the driving physics try to force the body down on the wheel (eg on poorly surfaced roads), predictive active suspension counteracts this effect. An extremely sharp impulse – as encountered on the racetrack, for example – will produce a very short but high energy demand of potentially up to 6 kW. Depending on the driving situation, up to 3 kW can also be fed into the 48-volt battery.
In conjunction with the air suspension and Audi drive select dynamic handling system, predictive active suspension in the A8 enables an unprecedented spectrum for driving. In the DYNAMIC profile, the sedan acquires the handling of a sports car. It turns in firmly and when cornering fast with 1g lateral acceleration, the body roll angle is just 2 degrees – as opposed to more than 5 degrees with standard suspension. In every driving situation, the rolling moment is optimally distributed and dive when accelerating or braking is reduced to a minimum. The result is a sporty quality of self-steering in the neutral to slightly oversteering range.
Looking ahead to predict
With the COMFORT PLUS profile selected, bumps in the surface are effectively ‘flattened’. The predictive active suspension works together with a front camera to identify uneven surfaces before they are reached and predictively regulates the active suspension. Even before the car hits a bump, the predictive function developed in-house at Audi signals the correct positioning travel to the actuators and actively adjusts the suspension. This reduces body movement and compensates almost entirely for long road undulation or similar unevenness.
This complex process takes just a few milliseconds: the camera generates information about the surface properties 18 times a second. The electronic chassis platform processes the road surface data and precisely actuates all suspension components almost in real time.

Enhanced safety too
Predictive active suspension also increases passive safety in combination with the ‘pre sense 360°’ safety system. It operates in conjunction with the central driver assistance system which uses the merged sensor data to identify hazardous situations around the car.
In an impending side impact at more than 25 km/h, the active suspension raises the body by up to 80 mm on the side of the impact. This brings the sill into a better position to absorb the impact energy. Deformation of the cabin and the loads acting on the occupants, above all in the chest and abdominal areas, can thus be reduced by up to 50% compared with a lateral collision in which the suspension is not raised.

Concept vehicles are built by carmakers for various purposes; some are intended to test certain styling ideas while others are a preview of a production model that is just around the corner. Sometimes, especially if targeting owners who are enthusiasts, a concept vehicle may show what more can be done or added to make a model more visually exciting or more capable.
Capable SUV made more capable
With the Lexus GXOR concept, Lexus worked with a company called XOverland to create a one-of-a-kind LX460 SUV that has accessories which enhance its looks and performance off-road. As it is, the LX460 is a very capable SUV since it rides on the same platform as the current Toyota land Cruiser Prado.
The customized vehicle starts off with a matte metallic gray and exclusive GXOR graphics. Incidentally, ‘GXOR’ refers to ‘GX Off Road’, which is the name of a group of owners. Lexus surprised them with this special vehicle during one of their recent events.
Accessories fitted
Some of the accessories installed include Lexus F Sport Wheels fitted with General 275/70×18 X3 tyres, Icon Vehicle Dynamics 2.5 CDC with remote reservoirs and billet control arms featuring Delta Joints, CBI Custom Stealth Winch Bumper, Frame Sliders and skidplates, Warn 9.5XPS Winch, and Maxtrax MKII Recovery Boards. All these items are available in the market for owners to install themselves.
On its part, Lexus will also have its own off-road package although, being a factory offering, it is more focused on comfort and reliability aspects rather than providing more off-road performance.
