Honda's latest EV concept is a two-seat roadster

Honda is a company that loves to tease us with relatively cool concepts, then dump blandness on the masses when it comes to production vehicles. The company has killed off true sporty cars (Prelude, Integra, and RSX) and outright sports cars (NSX and S2000) in the past decade. What we are now left with are the Civic Si and CR-Z (at least in the United States).
With all of this carnage in its wake, we have to look at Honda's latest concept with a cautious eye. The company today unveiled its new EV-STER roadster concept at the 42nd Tokyo Motor Show. The roadster is fully electric and features a 10 kWh lithium-ion battery pack that's good for 100 miles.

The rear-wheel drive concept -- in theory -- is capable of reaching 37 mph in 5.0 seconds. Given this odd choice of acceleration numbers, we'll have to assume that its 0-60 mph time is rather dreadful. And for those looking to blast down the highway at triple-digit speeds while thumbing your nose at the law, you'll be held back by a top speed of "only" 99 mph.
Although Honda hasn't given an official curb weight for the EV-STER, it says that it makes extensive use of carbon fiber to keep weight down to improve performance and battery range.

We still have faith that Honda will return to its glory days (the 1990s) and bring some lovin' to car enthusiasts, but we won't be holding our breath for too long. But then again, archrival Toyota did answer the call

Well I agree with you Brandon about the looks, but I don't think the solution is to throw 18's" on it. The answer for that is a "ground effects" body trim kit. They were all the rage when I used to be into modding cars, not sure about today, but I think there would be something available.

The main reason for the move to larger wheels is the fact that auto manufacturers have been jacking up the beltline of vehicles for years to adhere to increasingly stringent side-impact crash regulations

Hmm is that the reason? I always assumed the biggest advantage to larger wheel sizes was that they average the road surface over a larger area so small bumps and potholes are not so noticeable. Also larger wheels help with fuel economy because the lighter the wheel, the less is the kinetic energy of the wheel at a given speed and so the more of the work of the engine is used to drive the car forward. But the larger the diameter, the less revolutions are needed to maintain a given speed.

It's a big balancing act for engineers to choose between ride quality, performance, economy and suspension geometry. I've seen a lot of people who went against the engineers and did things their way, with horrible results.

I thought that it was the opposite when it comes to larger wheels with regards to ride quality? Larger tires typically have shorter sidewalls which contribute to a harsher ride. A thicker sidewall generally absorbs more road harshness.

As for ground effects, KILL ME NOW! Good gawd I hate ground effects with a passion :)

I think this is true. I saw a piece recently where the reviewer hated the larger wheels because they are more easily damaged by potholes since they typically have shorter sidewalls.

The wheels were damaged more easily because the tires had less sidewall height. You see 35 series tires out there and the road surface is like 2 inches away from the rim. Add to that lower series tires support less weight for a given size, a fancy way of saying they bottom out easier.

Larger tires typically have shorter sidewalls which contribute to a harsher ride.

The lower the series number (smaller the sidewall) the more ride harshness, but also faster steering response. Overall diameter is not really not that much of a factor. Sidewall flex is what's being addressed. The series number is the fraction measurement with regards to the tires tread width. A 50 series tires has a sidewall that is .50 of the tread width.

Now that ABS is common one is forced to maintain the overall wheel and tire diameter to within .5 inches of the original spec to perform properly. This is why you'll see 45 series tires on 17 inch rims, with an option of 35 series tires and 18 inch rims, sometimes with the smallest of tread width increases, depending on the numbers.

I went from a 205/65/15 to a 215/55/16. The OD was extremely close. But for a few years I had more fun riding on 225/50/16's, which looked downright massive compared to stock.

Prior to ABS you could do whatever you wanted, if the overall diameter increased or decreased you lived with it, along with the results.

Good gawd I hate ground effects

I'm not sure what's worse, that or color coordinating the car so that R2D2 looks right at home riding in it.

In general you don't increase the overall diameter of the wheel/tire combo because it will throw off your speedometer. Also, larger wheels are heavier and increase unsprung weight as someone mentioned above. This usually has a negative effect on handling, ride, fuel consumption, etc. And it is definitely easier to damage larger rims on potholes, especially in winter. I don't have anything crazy in terms of big wheels on my car (245/45/17) and I've busted a couple of tires and bent a rim or two on the lovely roads here in the tri-state area. One of those times the guy behind me had 19's on his Altima and some rubber band wheels. He hit the same pothole I did. I had one flat tire. He had two and a bent rim.

There are a lot of good reputable companies out there who will probably be selling good coilover setups for this car. I would lower it myself as well. I hate the 4x4 look on some cars out there today. IMO though, going to bigger wheels with the same wheel gap makes most cars look worse.
