Default Subaru Shows Turbo Hybrid B5 Concept @ Detroit Auto Show

I figure I owe yall some true news...



The name certainly doesn’t roll off the tongue, but the Subaru B5-TPH is sweet to say because of what those letters stand for – Turbo Parallel Hybrid. The TPH drivetrain consists of a 10kW electric motor sandwhiched between the transmission and turbocharged boxer engine. The gasoline engine produces 256 hp and 253 lbs-ft of torque, while the electric motor antes up another 111 lbs-ft of torque. That extra torque is provided by the electric motor at low speeds while the turbo spools up, effectively eliminating turbo lag. The engine also employs the Miller cycle, which increases the engine’s efficiency up to 30 percent by leaving the intake valve open for part of the compression stroke, which shortens the cycle's compression stroke. All of this leads to a combined estimated mileage of 40 mpg and a whopping good time when you mash pedal.

I dont really like the front end styling...or the color for that matter. I guess i would have to drvie one to get a real feeling for it. Have they said anything about how much it would weigh with all that hybrid junk in there? I wonder what kind of AWD system they would go with, or what the STi version would bring to the table......ahhh questions....

Miller cycle engine = Mazda Millenia S

Still, it's good to see Subaru experimenting with other internal combustion engine technologies

Has anyone watched the MSN videos for this? I watched the Camaro roll out with all of its glitz and glamour then Subaru comes on and they have a Japanese Exec, no models and no music debuting this car. It was funny.

Incidently... "all that hybrid stuff" shouldn't be that bad at all weight wise. Some lightweight batteries and a small motor between the engine and transmission and you're good to go Can't wait to see a production car that uses the technology.

if you could put an "amplifier" up to some subs to make it hit hard... Could you put an amplifier up to an electric motor to make it faster?

Technically... Yes... There will be a whole new "Tuner Revolution" around electric cars... I just don't foresee myself screwing around with that much electricity...

I'm just waiting for somone to loose control of their Prius, and drive it into a swimming pool... Instant Kiddie Stew!

Hahah! kiddie stew!

But that sounds kinda...dangerous. Anyone wanna pioneer electric tuning with me? We can go find a broke down prius or that honda hybrid. Go steal some Amps from the local gangsters, and have a....14sec hybrid!

You've got the right idea, and its called a VFD, variable frequency drive, my guess is the pancake motor is a 3 or 5 phase 50V induction motor or brushless DC motor with solid state VFD using IGBT's and PWM. To really stretch the analogy, It will be like a 6 or 10 channel class D amplifier with a pair of channels bridged for each phase. Sort of. With a very small frequency response, probably less then 200Hz.

http://www.powerpulse.net/features/a...a_022800e2.jpg

of to the left of the above diagram is the battery or capacitor, and the right is the motor (or generator when breaking). Power flows left to right during acceleration, and right to left during breaking. The key part with a motor/drive setup is full torque at zero speed. You don't need high HP to get decent acceleration, and you can have built in traction control. Just set the motor to ramp up to full speed without lossing load(back off torque when a wheel spins.

I've been in a concrete room when an solid state drive that was in "testing" decided to pop and IGBT or two. IT sounds like a shotgun going off, about 4 feet from my head. My ears rang for days.
