DeltaWing Racing Car Selected to Run at LeMans in 2012
We know it's been a long time since you've heard from us but, as promised, the DeltaWing racing car is moving from concept to reality! The following announcement was made today:
"We are pleased to announce a licensing agreement with the "Project 56 Partners" to utilize the DeltaWing design and technology for their participation in the 24 Heuers du Mans in June, 2012," said Ben Bowlby, the concept's originator. The Project 56 group includes Dan Gurney's All American Racers, Dr. Don Panoz and Highcroft Racing.
This marks a very important milestone for DeltaWing - we hope you're as excited as we are! To read more about this exciting development, please visit www.deltawingracing.com.
We'll be sure to keep you informed as major developments occur on the road to LeMans!

All the best,

KEY TECHNICAL FEATURES粗略翻譯，希望冇錯
- Engine and transmission are “non-stressed members” in the chassis structural design which allows the installation of a wide variety of lightweight powertrains.
引擎和傳動系統為安裝在車身上的非承載組件，以此降低動力系統重量(傳統方程式和Prototype均把引擎和變速箱作為車架一部份，直接連接車體和後橋) - The car features a 4 cylinder 1600cc liquid intercooled turbocharged engine that will produce approximately 300 horsepower at 8,000 rpm and weigh 70kg.4氣缸1600ccTurbo引擎，水冷式中冷器，8000轉時峰值馬力300匹，重70kg(比F1要輕啊…)
- Transmission is a 5 speed plus reverse longitudinal design with electrical sequential paddle shift actuation. The differential features an efficient variable torque steer/differential speed-controlled planetary final drive reduction layout with the entire transmission weighing only 33kg.
5前速連後檔，長身變速箱，電子撥片式，並備有主動差速轉向功能(相信用來補足窄前輪轉灣能力較弱)，傳動系統總重33kg - Vehicle weight distribution is necessarily more rearward than traditionally seen with 72.5% of the mass between the wide track larger rear tires.
後軸必須獲得最少全車72.5%的重量分佈 - 76% of the aerodynamic downforce acts on the rear of the car which has a lift to drag ratio of >5.0.
76%下壓力在車尾產生，下壓力-風阻比例>5.0 - Rear wheel drive coupled with the rearward weight and aerodynamic distributions greatly enhances inline acceleration capability.
後輪的重量和空氣動力平衡有助獲得極佳加速性能 - Unique amongst today’s racing cars, more than 50% of the vehicle’s braking force is generated behind the center of gravity giving a dynamically stable response.
與現時賽車不同，大於50%的制動力在重心以後位置產生，有助提升穩定性 - Locking propensity of the un-laden front wheel at corner entry is greatly reduced due to virtually no lateral load transfer with the narrow front track/wide rear track layout, steered wheel “scrub drag” moment is virtually zero greatly increasing tire utilization and reducing mid turn understeer.
前輪負重過大及鎖死幾乎完全不會發生，因為前窄後闊的設計使前輪不會受太多的橫向壓力。而其所產生的瞬間阻力接近零，大大提升輪胎的使用效率，並避免了灣中的轉向不足 - Advanced computer modeling of structures, impact energy management, aerodynamics, vehicle dynamics and tires has been used to develop the DeltaWing design.先進的電腦成型，撞擊管理，空氣動力，車輛及輪胎動態均被應用在Deltawing上
- Driver position, restraint layout and energy absorbing structures designed to meet the latest occupant survival criteria.
