Milner to Introduce E-REV Prototype Alongside Flying Car Prototype at New York International Auto Show

Milner Motors is introducing an initial driving prototype of the Milner ElectriCar—an Extended-Range Electric Vehicle, E-REV) alongside the prototype Milner Motors AirCar at the New York International Auto Show.

The ElectriCar, based on the same basic design developed for the AirCar, is a four-door, lightweight vehicle designed to cruise 100 miles (161 km) on power from an 11 kWh battery pack at speeds up to 85 mph. For trips greater than 100 miles, the batteries will be charged en route by a small gasoline-powered generator, currently spec’d as a 125cc, 15hp unit. Two 48V DC motors will provide 40 hp peak, 15 hp continuous power.

Milner recently completed aerodynamic testing on the ElectriCar to determine the amount and coefficients of aerodynamic drag and rolling resistance. The rolling resistance is currently higher than desired (.022 versus .006—requiring 5 hp to overcome rolling resistance at 60 mph). Aerodynamic resistance was computed at .209 and with a cross sectional area of 1.5 m2, the CdA was computed as 0.313, or requiring 5 hp to overcome aerodynamic resistance at 60 mph.

The AirCar is a four-seat advanced-composite car designed to be able to fly to a destination, fold up its wings, and drive down the highway. The Aircar features a foldable main wing in the rear of the vehicle and a canard (smaller wing) in the front.

When airborne, the 28-ft wingspan, 3,000 lb. maximum weight AirCar will cruise at 200-mph for up to 1,000-miles. Power comes from two rotary engines that drive dual 28-inch pusher ducted fans. Once on the ground, the wings fold to 7-ft wide and a separate 40-hp engine powers the car up to 85 mph. The initial prototype is non-flying but drive-able.

The similarity of design objectives among both vehicles—and the re-use of numerous  components—is at the core of Milner’s vision.  Milner holds patents on both vehicles.

how many flights have been made, is there footage? Seems a great idea.

The major car makers are all working on flying cars:

Lol.

I liked what I was reading until I got to the Air car part. A waste of resources and not practical for the foreseeable future. If they put all the energy into the ElectriCar and made it affordable they would really have somethin.

The air car is like the water car, they are usually not very good at either. A nice light streamlined electric car sounds good.

Light electric cars like Aptera and Loremo grab attention. If they can show that they are designed for safety and the price is right, they might sell some.

eric

the fairing over the rear wheels has a wing cross-section (unsuprisingly, given the car's origins). how much lift will that generate at 85mph? enough to make the car unstable?

Rotflol.

I love this car, but some of the streamlining looks kind of 1930's. The wheel fairings could be much improved, like Matt Weaver's bike: http://www.speed101.com/photos.htm#KyleEdge

Although some people don't like this kind of styling, I think there are enough people that do to sell enough.

And the 125cc genset is perfect!

It would be interesting to see any crash tests done on these cars. A semi-truck would probably crush these vehicles like soda cans.

TC

A semi-truck will crush anything like a coke can not just small cars, so its pointless to compare.

Patrick

Loremo, Aptera or this... Seat 3 people, do well on crash tests and do it for a reasonable price ($30K to $40K).

Patrick

Hmmm, they are just now looking into crash worthiness. I forsee the 1250lb weight of the vehicle ending up at closer to 1500lbs when all is said and done. Still good enough to me.

John Taylor

Good idea, fine numbers in the specs.

Styling is a bit gimmicky with the holdovers from the airplane being incorporated into the car. Still, it might be ok in a small number of situations.

I would rather see a full Electric car being built that did not take it's origins from some other bit of machinery.

FAA says- drive car on road, fly plane from airport

Gerald Shields

All this talk about aircars makes me wonder if it was possible to place a small runway on any major highway. The runway would function as a version of a "off/on ramp" for aircars. Then you marry that with NASA's Small Aircraft Transportation System (SATS), then maybe it would make some sense.

Forgive me for going off topic.

Looks like it should be in pictures. This car will be sold as a kit car and avoid some of the fed's safety requirements. Still, it's not one to take the kids to soccer in. But kudos on imagination and serial hybrid drive train. 1000 mile E-REV (costume not included).

"the batteries will be charged en route by a small gasoline-powered generator, currently spec’d as a 125cc, 15hp unit."

I'm curious about mpg for gasoline-generator-battery-electric-motor vs gasoline-motor, anyone with data?

A gasoline generator is way simpler than gasoline car motor so I guess more efficient since targeting only one optimal RPM (but I could not find data). And battery can benefit from braking energy regeneration.

All in all?

Thanks in advance,

Laurent

Flying cars will only happen when: 1: Flying small vehicles can be made easy and safe (imagine drunk flying) 2: Make the flying propulsion system as quite as ground cars (close to impossible, unless anti-gravity comes around) 3: Fuel prices drop that can support a flying car infrastructure (All signs point to "NO"!)

First of all, thank you all for your comments. Regarding the comments:
1) The AirCar is a driveable but not flyable prototype. It demonstrates how everything fits together. Additional engineering work will begin later this year in building the AirCar as a prototype airplane once manufacturability studies have been completed.
2) The wings and canards on the ElectriCar are canted downward to offset the lift that the vehicle produces.
3) On any light vehicle, crash tests are a challenge. The 200 inch length and 45 inch height, the same as many full-size vehicles, gives us adequate space for crushability. The wide stance of the wheels provides great rollover protection, plus absorbs some of the side crash impact.
4) Runways being built near highways are not necessary, given that 5000 underutilized airports exist nationwide.
5) We do not yet have numbers on the efficiency of changing energy from gasoline to batteries to wheel energy. It seems to us that it makes more sense to use electrical power from the power grid for transportation, alleviating 95% of the need for gasoline emissions.
6) Although we feel we are making gradual progress, we have been careful to not claim more than we have accomplished. In the end it will be the consumer that decides how much merit our ideas have.

Smaller lighter aerodynamic battery powered cars are our future. This is an interesting offering and should be applauded as such.

But until our battery technology and/or our fuel cell technology advances far enough to challenge similar gasoline powered vehicles in range and chargeability, these ideas will only be dreams. Yet I am optimistic in seeing ideas such as these contributing to our overall future transportation needs. Keep up the good work!!!

Michael

Hello Mr. Milner,

thanks for your reply, all the best in your efforts. looks like much work has been put forth. but it appears you have far to go in investment, knowledgebase and work in comparison to your competitors.

What are your long term goals and are their any serious investors backing you?

John Taylor

@ jmilner
Nice to see you reading our comments.

1 ) I would prefer to see your plane first made without the fold up wing, and later add this option if it flies well.

2 ) The BEV development has some merit. If you cut off what is left of the wings, and keep the weight low, then you have a very nice little car. Offering a selection of battery packs will keep the base selling price reasonable, and still make longer range trips possible.
