    Lighter, Faster, Better

    Lotus continues to lead in weight loss race

    Over 200 kg cut from Lotus cars this year

    Unrivalled experiences in lightweight engineering

    Latest models continue the success story

    Lotus Evora Sport 410

    Having slashed a substantial 207 kg from its cars this year alone, Lotus remains the leader in the

    engineering of lightweight, high performance supercars.

    From the iconic Elise, through to the hypercar humbling 3-Eleven, every Lotus benefits from the

    companys approach to engineering in lightness at every stage of design and construction. With its

    heaviest model weighing in at just 1,395 kg, its still streets ahead of rivals.

  • Lotus Elise Cup 250

    With a heritage of efficient design, no other car manufacturer can claim a better track record when

    it comes to honing road and race cars. In its 68th year, Lotus still remains true to the ethos of the

    companys founder Colin Chapman, and his approach to design and construction.

    Lotus Exige Sport 350 Roadster

  • Leading the field in advanced construction techniques and technology, it has continuously strived

    to push boundaries. The names Chapman and Lotus remain two of the most important names in

    the evolution of automotive design with many innovations, including the GRP monocoque in the

    Lotus Elite, and the bonded aluminium chassis in the Elise. Lotus was also the first company to

    introduce a Formula 1 car constructed from carbon fibre.

    Today, Lotus cars are developed through the companys Lightweight Laboratory concept. Far more

    than just a part of the famous Hethel factory, this philosophy has grown to provide a framework for

    evaluating every component. Viewing components in isolation, as well as part of a sub-assembly

    and even the car as a whole, it allows each to be assessed, optimised and re-engineered. This

    approach means that each car represents the epitome of Lotus light is right approach.

    Lotus 3-Eleven

    Why light is right

    Jean-Marc Gales, CEO of Group Lotus plc, sees the companys approach to engineering as its

    biggest strength. Were not concerned with following other car manufacturers. Innovation comes

    from taking a new approach, and we dont stop looking. Colin Chapman famously said, Adding

    power makes you faster on the straights, subtracting weight makes you faster everywhere, and

    that thinking has become part of our DNA.

  • He continued, To perfect a pure sports car, you must consider weight your enemy. Lose weight

    and you will make significant gains: harder and faster cornering, better braking, greater agility and

    responsiveness, along with faster acceleration.

    Looking at a car holistically allows for all redundant weight to be removed, with every part serving a

    purpose. This includes the use of carbon fibre which, rather than included to just boost kerb appeal,

    must produce tangible benefits.

    Far more than just boosting straight-line performance, reducing a cars kerb weight allows for the

    correct calibration of the suspension. This allows sharper handling, and better body and roll control,

    but not at the expense of ride comfort and composure. The overall reduction of weight also allows

    for optimised weight distribution, a huge contributor to the poise and balance of a sports car during

    high-speed cornering.

    Lotus Evora 400

    Proving this principle, Lotus aluminium vehicle chassis technology is still considered the

    benchmark within the automotive industry. Utilising strong and stiff extruded and bonded aluminium

    sections the simplicity off the tub construction belies its benefits.

  • Lotus Evora front subframe

    Able to employ lightweight extrusions, joined by epoxy adhesive, its immensely strong and

    torsionally stiff, yet the chassis for the Elise and the Exige tips the scales at just 68 kgs.

    Lotus Elise chassis

  • Not only is this roughly half the weight of an equivalent steel chassis, its also substantially simpler

    to produce than a similar weight carbon fibre alternative and easier to adapt to the requirements

    of specific models.

    Lotus Evora chassis

    As an antidote to sterilised and attenuated modern cars, Lotuss approach continues to deliver a

    pure, undiluted driving experience. Avoiding systems that rob cars of their fun factor, including

    electric power steering, it places function over convenience, to produce truly involving vehicles. Its

    latest models continue the Lotus approach to light is right engineering.

    With a kerb weight of just 1,325 kg, the Lotus Evora Sport 410 cuts 70 kg from the Evora 400 and

    draws heavily on Lotuss experience with carbon fibre.

  • Lotus Evora Sport 410

    This includes a one-piece carbon tailgate, replacing five separate components on the previous

    version into one and saving 10 kg. Another 10 kg was saved by fitting a Li Ion battery, while the 6

    kg was shed though the addition of carbon sports seats.

  • The Lotus Exige Sport 350 weighs just 1125 kg and every detail of this latest version was

    reconsidered in order to save weight and deliver a superior car including a louvered tailgate (3

    kg), a redesigned gearshift mechanism (3 kg), a revised subframe (3 kg) and enhanced body

    panels (12 kg), resulting in a lower centre of gravity and further track-honed handling. Optional

    carbon composite components shed a further 30 kg, so allowing the new roadster version of the

    Exige Sport 350 to weigh just 1,085 kg, a reduction of 91 kg compared to the previous Exige S.

  • Lotus Exige Sport 350 carbon rear diffuser

    The latest versions of the legendary Lotus Elise, the Sport and Sport 220 have become lighter

    and even more performance-orientated. Both have both seen a weight reduction of 15 kg,

    including the standard lightweight sports battery, saving 3.5 kg and optional forged wheels saving

    5 kg, too.

  • Lotus Elise Sport 220

    The new Lotus Elise Cup 250 is the fastest road-going Lotus Elise ever, adding 26 hp and

    shedding 31 kg (with lightweight options) compared to the previous Elise Cup 220. Included as

    standard in the Elise Cup 250 are carbon seats saving 6 kg, ultra light forged wheels saving 1.5

    kg and a Li-Ion battery dropping the weight by a further 10 kg. A carbon pack (carbon rear, wing,

    front splitter, rear diffuser and floor extenders of components) reduces the weight of the car by a

    further 10 kg.
