ideate it ’s 30 instant before the greenish flag drops on Sunday ’s 51st Daytona 500 parentage car race .
earn you do n’t have near enough Buffalo annex , you attempt to set your own track record on the way to the supermarket . If only your cable car had some of that cutting edgeNASCAR technology , then you could make the trip in half the clock time and not worry about hitting a few mailbox on the way .

Actually , today ’s yield rider motorcar have adopt several foundation from bothstock carand Indy - style racing . Here are five of the most useful technology that have sped to the production line.1 . Keyless IgnitionWhen was the last time you saw Jeff Gordon dab down his pocket wonder what he did with his car keys ? Thanks to keyless ignition , he can crawl in behind the wheel , strike the switch and go . Several luxury passenger car are now offering a similar push - clit feature . Of of course , passenger cars involve to be a little more concerned with surety , so either keys , fobs or biometric organization are used to get inside the car.2 . Semi - reflex TransmissionsWhen watching a Formula 1 race on TV , you may have noticed how the number one wood shifts gears with the flick of a lever tumbler locate justly behind the steering roulette wheel . A mixture between automatic and manual transmittance , these unmediated shift gearboxes allow sequential shifting without deject a clutch treadle or move a shift lever tumbler through the traditional " H " pattern .
With a film forth from the equipment driver , the transmission move up cogwheel by gear mechanism , with downshifting check by flicks towards the equipment driver .
Now , this semi - automatic technology is available on high - end yield elevator car . gadget driver can prefer to take control of the shifting or let the computer do the work . The 8 msec it takes to go from one gear to another eliminates the " shift jolt " that pure manual transmissions do when the hold withdraw , then prosecute the engine . This smoother transition can also increase gas gasoline mileage by up to 10 percent.3 . Door cushioningIn a race car , seat belts and head / neck restraints protect the number one wood against front and rearward collisions , but a " T - pearl " or side collision can be even more dangerous as there is a much small " crumple " zone .
NASCAR’sCar of Tomorrow(CoT ) , which was tested in recent year in an effort to quash death and serious harm , is now the railroad car of today . Among its innovations , soften foam is insert into the door to absorb as much impact as possible . NASCAR chose a polystyrene foam material called Impaxx from Dow Automotive . Its gazillion of tiny air travel bubbles each engage some of the impact , lessening the vigor transferred to the driver .
Impaxx is now used in more than 2 million passenger automobiles.4 . Lightweight Body MaterialsTo be fast , airstream cars need to be powerful while weighing as little as possible . Yet , the stresses of high - fastness driving demand hard material . As substitutes for bed sheet metal , C fiber and aluminium now make up most of the body of a Formula 1 race car and have been bring in in strategical places on the CoT. For production cable car models there are fuel - saving opportunities as total car weights can be reduced.5 . Soft WallsFinally , the applied science with the majuscule potency to keep us safe is not even a part of the car .
It conduct the death of the sport ’s image , Dale Earnhardt , on the final lap of the 2001 Daytona 500 to jump - start the development of a more energy absorbing paries that surrounds the raceway . Earnhardt crashed head - on into a concrete bulwark at 180 mph .
The Steel and Foam Energy Reduction ( SAFER ) roadblock — developed at the University of Nebraska , with funding and support by the Indy Racing League — dissipates the push of a crash aside from the car and driver . It is a system of structural brand tubes stake by Owens Corning Formular 150 froth with exchangeable property as Impaxx foam . This system is placed in front of the exist concrete walls . Since the first SAFER wall was instal in 2002 , there has not been a serious injury to a driver , despite many soft wall crashes .
Several state main road departments are now evaluating the technology for use along grave stretches of thruway .
