Lotus Engineering is currently developing an engine concept called the OMNIVORE together with the Queen’s University Belfast and Jaguar Cars Ltd. The OMNIVORE research engine features a variable compression ratio, direct injection and a two-stroke operating cycle. It will run on a mix of petrol and alcohol.
Group Lotus plc CEO Mike Kimberly says alcohols possess superior combustion characteristics to gasoline, and taking full advantage of the benefits of bio alcohols will ensure a larger amount of fuel burned will comprise of renewable fuels.
More details will likely come later when an actual working concept is ready.

Good to see Lotus working on something new, hopefully it’ll trickle down to Proton.
FIRST!!
Why two stroker? They are making motocycle engine? Or this is for car?
Rexis,
2 stroke engine contains less engine components compared to 4 stroke engine and lighter. it will produce more torque and power with lower CC compared to 4 stroke engine. the problem with the 2 stroke engine is the lubrication, I guess the engineer at Lotus and Jaguar has already have the solution. You can start figure out what is the benefit of having lightweight engine.
most importantly proton to have the kind of engine is continously tuned at every rev range so that the torque band is stay high at any revs,
thats what the modern engine does, suffix like i intelegent C continous D dynamic means that the engine is tuned its ignition, timing, valving, at every range of engine speed and load, very useful at lower end,
for the cps or v-tech cam changing like is an extra for higher power band is an extra gain,
and the VIM covers generally said between the begining of the rpm towards 3500 where the most usable range for everyday use, of course it does cover lower ends,,, but generally not thoroughly,
but i ,C, D will raed and changes at 0 500 1000 15000 2000 2500 3000.. or even at a very closer intervals therefore we can feel livelier and the delivery is at the very tad of the pedal, the character does enhance batter fuel economy and lower emission,
good work there Lotus.
so,, this continous valve control ,so far i havent found it by lotus,
of course it has CPS, thats great
but what matters is continous valve timing control is almost todays standard, as far as the fuel efficiency counts,,, where it is by lotus engineering?. how do we aquire such technology,?
when most people now are talking about technology and efficiency,
this aspect is also part of the determination of resale value of a car.
clearly what happened now late lotus car employs toyota engine, as found in late exige and its latest evora,
this need to be solved by proton
Very innovative – interesting!
lotus so good, why is proton so shitty?
Proton is not shittyla, bird-brain. Proton owns Lotus. Lotus may have the tech think-tank, but they are useless when it comes to profitability- which people at Proton is rather good at (in any case, it’s better than Lotus’s idea of profitability).
Anyhow, I’m all for any sort of engine configuration (4 or 2 -stroke, so long as the prerequisites are satisfied). And that is good fuel economy, strong performance and reliability.
PROTON SUCKS: you buy a decent book, but you never read it, doesn’t mean you will learn anything from the book.
catchcart: Ahh, i see, lightweight and more power compact. It is interesting how they able to make it to meet euro emission standard.
SatriaGuy, yea, very profitable, when this stupid barisan nasional fucked up the whole malaysian car industry by charging crazy import taxes on imported cars, giving poor people no choice but to use the lousy protons
Why does Lotus even bother with biofuels? It is already widely established that biofuels do more harm than good.
