Hybrids not necessarily better than diesels, says Emissions Analytics

  A bit biased? They should compare hybrids with diesel autos (because the hybrids are). Who funded it?

  My friend has a hybrid Lexus 200h with a 1.8 engine, my ageing diesel X Trail 2.2 still does better MPG than his car, so I am not surprised by this at all

  I'm no supporter of Hybrid technology but there is a fundamental flaw in your survey. Both hybrids are automatic and 7 from 8 of the diesels are manual. In reality whilst autos are so much better than they used to be, where both manual & auto are available in a car the manual remains the more frugal. So com on, compare eggs with eggs

    @Weave - it's a fair point - although a driver opting for a hybrid wouldn't necessarily opt for an automatic if they were choosing a diesel. On the other hand, petrol hybrids would have a fuel cost advantage.

  No one manufacturer has claimed that a hybrid offers better fuel consumption over a diesel but they all claim that they are far better for the environment as there is less CO2, near zero NOx and no particulates that a diesel spews out by the exhaust full, I think the point has been completely missed here about the advantages of a hybrid vehicle over diesel!! Also shame on FN for not doing a like for like comparison, knowing full well the results would be majorly skewed by manual over auto...tut tut tut

    @Goob_It - Do't forget that the CO2 values of diesels compared to petrols per CC is in fact much lower. A petrol 1.8 produces higher CO2 than a diesel, even a hybrid if its not running on batteries. The only real advantage of petrol over diesel is the particulates levels

  Also funny how it was only Toyota Hybrids that were compared, clearly not a fair test, where are the other manufacturers who have hybrid models???

  Not forgetting of course the price premium for Diesel over Petrol when making the comparsons over actual MPG's

  1. The CO2 claims in favour of hybrids are not relevant. Actual CO2 emissions are inversely proportional to actual mpg. Higher mpg means actual emissions are lower. Simple chemistry GCSE stuff. 2. Does any manufacturer produce a manual hybrid? I thought they are all autos. 3. Don't forget the huge environmental damage from the manufacture of lithium ion batteries. They are about the least green product around.

  No real surprises here! Despite the widely published views of Boris Johnson and a few others, modern diesel engines are clean and very efficient. Hybrids do perform well around town because electric motors provide high torque at low revs so are very efficient in stop start traffic where as internal combustion engines need to hit relatively high revs to get adequate power to move off which makes them less efficient. The problem with hybrids is that they are hybrids so they have two propulsion systems which adds a lot of extra weight and makes them far less efficient once travelling at higher speeds. The solution is simple: If you spend most of your time driving in heavy traffic, you buy a hybrid. If the majority of your driving is on motorways you don't. The problem is that the politicians and green campaigners only see it from their own perspective and want one solution for everybody, so instead of "One size fits all" you end up with "One size doesn't actually fit anybody".
