BMW's i8 will launch in the U.S. in Spring 2014

BMW has officially taken the wraps off its new i8 plug-in hybrid sports car, after teasing it in concept form for the past two years. The two-door, four-seat vehicle makes extensive use of carbon fiber to keep weight down to a relatively respectable 3,285 pounds.
 
The production version of the car makes use of a turbocharged 1.5-liter three-cylinder engine producing 231 hp (236 lb-ft of torque), which is sent to the rear wheels using a 6-speed automatic transmission. The front wheels are powered by a 131 hp electric motor (184 lb-ft of torque) paired with a two-stage automatic transmission. Those two engines combined give the i8 a total of 362hp and 320 lb-ft of torque.

 
This complex arrangement allows the i8 to dash to 60 mpg in 4.4 seconds, while still offering an EPA estimated 94 MPGe. The i8 features five driving modes that can be selected using the "Driving Experience Control" switch. The most efficient mode (with the vehicle operating as front-wheel drive) will allow the vehicle to travel up to 22 miles on battery power alone at speeds up to 75 mph.

 
Thanks to having two engines, two transmissions, lithium-ion batteries, and copious amounts of carbon fiber onboard, the BMW i8 most definitely isn't cheap. The vehicle will be priced at a whopping $135,935 when it launches in the U.S. next spring.

No it's not a joke post and I agree with you that people use a sports car for normal driving, I never denied that. I explicitly wrote and even highlighted that I'm talking about 'road traffic' to exclude racing tracks.
I just think that such expensive sport cars get more used for fun driving on a normal road than for shopping in a city or making a vacation several thousand miles away. (both perfect scenarios for the use of a hybrid).
I just see little use in a hybrid in such a car priced that high.
Either full electric or traditional gasoline, especially because the BMW i8 gets touted as an innovative futuristic car.

Unlike ICE engines, electric motors have zero time to wind up to full power. With ICE engines, you hit the gas, fuel is released, combustion occurs and that pushes the pistons. It takes a few seconds to get to full power. Electric is at full power near instantaneous and they work awesome in a sports car. You will see more and more of this on the high end. The thing with hybrid's is it depends on how you work it. It can either be set up for fuel efficiency, or for extra power/torque.

maybe for cheap cars or old cars. The new sports cars these days have almost instant throttle response. BMWs are probably most impressive even with their turbo motors. There's almost no turbo lag. I have a 135 coupe right now.

I don't know what you mean by full power as Power = torque x rpm/5252. So full power can only be achieved at a specific rpm.

do you mean full torque at a specific rpm?

Yes, that's exactly what he meant and you know it.

I dont think you quite get the tech, or the point of this car.

IMO, the point of this car is to showcase technology. It does that. Whether or not it makes sense is irrelevant. Someone will buy it and BMW can add a couple of bucks to their marketing budget. On a side note, I understand that the 918 Spyder hasn't sold out yet but the LaFerrari has. Hmmmm.

this is a sports EV in marketing. It is not meant to be anything besides a status symbol or a statement for the rich.

It is pointless to discuss how much of a sports car or practicality it has.

it will barely make a dent on their CAFE fuel economy average.

The way it is calculated is inversed and also used number of vehicles as well. For a low volume vehicle like this, there's little changes to the average fleet mpg.

The formula is on wiki if you want to look it up. I'm sure this has already been discussed on DT before as well.

You're right that it's underwhelming. I'm pretty sure only the rich or celebrities would buy this to say they're green and awesome.

No one will buy this car! Celebrities have at least some intelligence... This car is blasphemy!!
