Line-off Ceremony for Auris Hybrid at UK Plant

Toyota Motor Manufacturing (UK) Ltd. (TMUK) held a line-off ceremony today to mark the start of production of the Auris Hybrid (earlier post). TMUK will produce 30,000 Auris Hybrids annually, with sales of the vehicle beginning on 1 July 1. Plans call for the vehicle to be sold in 32 European countries.

Key to the successful installation of Hybrid Synergy Drive series/parallel full hybrid system within the Auris front-engined platform is the housing of the electric motor, generator and power split device in one transmission casing the size of a conventional gearbox. The full hybrid drive system’s electric continuously variable transmission is controlled by shift-by-wire technology, using an electric shift lever system.

System power is provided by a lightweight, compact, 4-cylinder, 1798 cc, Atkinson cycle VVT-i gasoline engine developing 98 DIN hp (73 kW) at 5200 rpm and 142 N·m (105 lb-ft) of torque at 4000 rpm, and a high performance, permanent magnet, synchronous 60 kW electric motor generating a maximum 207 N·m (153 lb-ft) of torque from 0-13,000 rpm. Combined cycle fuel consumption is calculated to be 3.8 L/100km (62 mpg US), with CO2 emissions of 89 g/km.



thank god other hybrid to chose


At a realistic price for atmospheric carbon sequestration of 100$/ton (via biochar production) and a CO2 emission of 100g/km, the cost for sequestration of the CO2 of 10000km driving would be 100$. To sequester all the CO2 a car emits over its average life of 200.000 km would cost only 2000$. (a by-product of it would be increased soil-quality and an incentive for high-ecological-value agriculture)
Try to make a zero-emission car in any other way for 2000$ more than today’s hybrids !

It is perfectly possible to cut net carbon-emissions of car-use to zero with the technology of today. The only thing we need is a price on CO2. We can even keep using fossil fuels, as long as that carbon is completely sequestered. Although I like full-electrics of course, this should not be an excuse to delay easy action we can do today.
The CO2 problem of transportation fuel is purely a problem of political will, not a technological one.


Why would you buy a hybrid Auris rather than a Prius ?
Is it cheaper ? shorter ? Less obviously green?

My guess is that it is a green "range topper" to make people buying ICE Aurii feel better about themselves, much the same way that the Golf GTi sprinkles magic on the whole range, even if relatively few GTis are sold.


I don't understand why they would put in a 60 kW motor and only 1 kWh worth of batteries. I guess the PHEV conversion crowd will like it.


@ SJC,
"...60 kW motor and only 1 kWh worth of batteries..."

With power density of NiMH about 1kW/kg and energy density 65 Wh/kg (Cobasys, new Panasonic perhaps more), 1kWh of batts can provide about 15 kW of power. There is in HSD also MG1 (generator-starter) rated at 10-13kW (off-hand value), driven by ICE.
I noticed some large ultracap modules (high-voltage ones) as part of Prius power electronics module (in a picture). We can safely assume they can provide another 10-15 kW for 2-3 sec during acceleration (until emptied).
So it all adds up to about 40 kW of supply, for a short period of time.
Motor (MG2) rated at 60 kW is usualy peak value, not continuos. That small motor (air cooled) is not likely to sustain more than 30 kW continuous. To me it sounds a reasonable design choice.

I think its actually 1.6kwh, Honda is 0.5kwh.

The reason for the small battery is cost, batteries are still expensive.

The Toyota hybrid achieves diesel like efficiencies (and higher) but with much simpler emission control systems.. I think its a cheaper way to do it (vs diesel) and Toyota is making a killing on the profits. Plus the green cachet, regen braking, low particulate count and possibility of all electric range.


It would be nice to have modular battery packs. I can buy it with 1 kWh and add in 1 kWh increments if I choose. At some point with the proper programming, I can start to capture some more regenerative braking energy and use the motor more aggressively.
