The Golf TDI Hybrid concept (earlier post) introduced by Volkswagen at the Geneva Motor Show combines an advanced diesel engine with an electric motor and the latest generation of VW’s seven-speed DSG gearbox. The hybrid concept vehicle is capable of achieving 3.4 L/100km (69 mpg US) of fuel consumption.
At the core of the new Golf TDI Hybrid is a 1.2-liter three-cylinder common rail TDI diesel engine developing 55 kW (74 hp) and 179 Nm (132 lb-ft) of torque. Working either in tandem with the diesel engine or, if required, on its own in all-electric mode, is an electric motor developing 20 kW and 140 Nm (103 lb-ft) of torque. The electric motor also replaces the conventional starter motor and alternator to save weight and improve packaging.
The motor can also operate as a generator, recovering kinetic energy from the car during braking to charge the 220 volt, 45 kg nickel metal hydride battery which has a capacity of 1.4 kWh.
In practice the electric motor powers the vehicle from standstill with the diesel engine only engaging should additional acceleration be required or at higher speeds. In these situations the diesel engine takes over with the electric motor only working if required to supplement the combustion engine – for example, during overtaking manoeuvres. When at a standstill the diesel engine shuts down completely to conserve fuel and increase efficiency. The energy split is relayed to the driver and passengers through a graphic display accessed through the touchscreen satellite navigation screen.
Drive on the concept car is channeled through the new seven-speed DSG twin-clutch gearbox. This features a pair of dry clutches as opposed to wet clutches.
Visual changes which differentiate the Golf TDI Hybrid include a new, unique grille design, smaller front air intakes to reduce aerodynamic drag and ‘TDI-Hybrid’ badging. The Golf TDI Hybrid also sits lower than the standard Golf on revised suspension and adopts the front splitter from the Golf GTI Edition 30 to help further reduce aerodynamic drag.
The Golf TDI Hybrid is currently a concept vehicle, but Volkswagen says that a version of this vehicle is likely to go into production in the future.
This study follows the recent launch of the efficient new Golf BlueMotion. Adopting an optimized 1.9-liter, four-cylinder diesel engine linked to a revised gearbox and more efficient aerodynamics the Golf BlueMotion can achieve a combined 4.5 L/100km (52.3 mpg US) while emitting just 119 g/km of CO2.

Rest In Peace, old friend, your work is finished.....
If you want ON or OFF the DIESEL ”KnOcK” LIST just FReepmail me.....
This is a fairly HIGH VOLUME ping list on some days.....
VW DIESEL-HYBRID KnOcK!........
How many hamsters fit in that engine?
The price of diesel is higher than premium gas.....can anyone say “RIP-OFF”?
Sign me up, I just paid $3.64 a gallon last light.
Even though the price of diesel is higher than gasoline, it’s STILL MORE ECONOMICAL. Do the math............
Hey, it has more power than my 50 hp ‘79 Rabbit diesel.
Done!...........
“The price of diesel is higher than premium gas.....can anyone say “RIP-OFF”?”
Yeah but you’d be getting over twice the MPG of your avg car with a car like this so you’d be back at the pump less often.
I have heard they will put that same engine in their new Mid Sized SUV due out in the summer.
Concept, eh? So it will be 4 or 5 years till VW makes it? Isn’t Honda coming out with a diesel hybrid next year?
I drove my son’s new 2008 Rabbit the other day. The 6spd Tiptronic in there is a blast to shift.
When are they available?
Honda Diesel is coming this year.............
VW isn’t like GM and Ford. They actually put these “concepts” on the road..........
Seems like if you get into an accident, someone could get fried. Ouch!
NOT SO! We’ll still run ‘em in the Harleys!!!
THAT is a problem with ALL hybrids, now. EMT crews and Firefighters are just now training to dis-able these HV batteries before they use the Jaws-of-Life and accidentally cut thru a power line. Could cause an explosion if there is leaking fuel. But not nearly so dangerous with diesel fuel.......
As a kid, my dad’s ‘79 Rabbit Diesel got 55 MPG. We had our own fueling tank at home. We were all set.
Seems that 14 MPG improvement is not much in 30 years.
Indeed it is.
Recall that in the late '70s, diesel was selling for about 45 cents/gal, while gasoline was about 65 cents/gal. People started buying German diesels, and GM came out with their first diesel cars and light duty trucks.
Then came the Iranian revolution, May of '79.
Ta-da. Overnight, diesel went from 45 cents to 90 cents or so, and gas slid over a dollar.
The oil companies made sure that no one could escape just by purchasing a diesel vehicle.
No no. That would be too easy, dears.
At the time I worked for GM. We were not amused. The power play was so obvious, and the excuses so pathetic (for instance, even then, Iran was only like 3% of our supply, at most. How does the temporary restriction of that tiny amount add up to a doubling of cost?), you could only be angry. People who think this was just "market forces" are fools.
But if diesel hybrids become predominant (and they will in Europe), then the whole scam is going to be a bit difficult to maintain.
But we can all be certain that the OPEC countries and their western enablers will try.
I’ll wait for a diesel Hummer....
