')I would have to think that those would be some pretty significant mods to get that to work... but I'm the first to confess that engines are not my forte.
Do you mean the tourqe/power or the emission reductions? The car have been modified by a well known swedish tuning firm, BSR. They are known for their high power engines. They list in a swedish article modifications to the combustion chambers, fuel system and software. The reduction in emissions is almost only due to the fuel E95 (EtamaxD). The company
SEKAB makes and sells that fuel here in Sweden. It is about 95% ethanol and the rest is ignition improver and denaturing (MTBE, isobutanol).
Both trucking companies
SCANIA and VOLVO have made engines for that fuel in the past, mainly buses and the like. Now they have made new engines tuned for E95 that have close to the same MPG as the diesel ones! Despite that ethanol has less energy per liter. This is impressing IMHO.
BSR have made the same thing with a ordinary diesel car, they state that fuel consumption is almost the same on E95 as on ordinary diesel. I would think the consumption is noticably higher on E95, but it still makes for an impressive improvement in efficiency.
But I'm more impressed by the reduction in emissions. Would make diesels truly clean, as the particle problem on ordinary diesels is quite grave indeed (don't mention NOx or CO2

. I want a small commuter car with a small engine that runs on E95. It would have close to the same milage as a ordinary diesel one, but almost none of the harmful emissions. Fuel availbility is a question, though there are fillings stations planned already. See:

')Ethanol also for lorries
Both Scania and Volvo have developed lorry engines that can operate using
renewable ethanol. The Swedish bioenergy company SEKAB is planning to have
in place an initial network of filling stations for E95 by 2010. E95 is the fuel
used by buses and lorries in place of diesel.
"We already supply E95 to those towns that have ethanol buses and municipal vehicles
like rubbish trucks with ethanol engines," says Per Carstedt, CEO of SEKAB. “The lorries
use the same fuel as buses. This is a different blend compared to the ethanol used for
private cars (E85). Instead they have 95 per cent ethanol and five per cent ignition
improver.”
In the initial phase, there will be 6-10 filling stations for E95 along major highways like
E4 and E6 and at special lorry terminals. In two years, the fist ethanol lorries for long-
distance transports will be available on the market. As the number of long-distant
vehicles with ethanol engines increases, the number of filling stations will gradually be
expanded. Their exact locations have not yet been determined.
"We are assuming that the number will be sufficient to comfortably serve heavy lorry and
buses in national long-distant traffic," says Per Carstedt. “These types of lorries have fue
tanks that can hold about 1000 litres of ethanol. Since the new ethanol engines
developed by Scania have the same energy efficiency of diesel engines, their range will
be more than sufficient.”
SEKAB has previously built a network of filling stations and already supplies ethanol to
over 1000 filling stations for E85. The required investments in each new filling station ar
modest.
"We see no problems with guaranteeing a sufficiently effective distribution system the
day Scania and Volvo begin offering their customers heavy lorries with ethanol engines,"
says Per Carstedt.
For the next stage, SEKAB is planning to also develop E95 distribution on two other
major Scania and Volvo markets – Brazil and Great Britain. After this, the other Nordic
countries are judged to be most promising.
