From NOT A LOT OF PEOPLE KNOW THAT<\/a><\/p>\n\n\n\n

By Paul Homewood<\/p>\n\n\n\n

Following my post on the EU abandonment of the ban on ICE cars in 2035, it is worth clarifying the position regarding hybrids.<\/p>\n\n\n\n

Just to recap \u2013 the EU demands that vehicle emissions are cut by 90% from 2021 levels come 2035, that is from a 2021 baseline of 110 g CO2\/km.<\/p>\n\n\n\n

As an example, the current Volkswagen Golf diesel is rated at 115 g currently, with the Golf plug-in hybrid at 25 g.<\/p>\n\n\n\n

All emissions figures are certified by the manufacturer, using WLTP technical procedures. I would stress that they are tailpipe emissions, so fully electric cars are rated at zero emissions, regardless of the fact that the electricity they use may involve CO2 emissions.<\/p>\n\n\n\n

Where does this leave non-plug-in hybrids, usually referred to as mHEVs?<\/p>\n\n\n\n

Up the creek without a paddle, by the looks of it!<\/p>\n\n\n\n

The Golf petrol mHEV has emissions of 117 g\/km, as high as the diesel.<\/p>\n\n\n

\n
\"Volkswagen<\/figure>\n<\/div>\n\n\n

Clearly there is no future for cars like these under the 2035 targets.<\/p>\n\n\n\n

Someone, by the way, mentioned the Prius. This has an emissions rating of 36 g\/km, still way above the EU\u2019s 2035 Directive, which equates to about 11 g\/km.<\/p>\n\n\n\n

\"A<\/figure>\n\n\n\n
\"A<\/figure>\n\n\n\n

As I mentioned before, plug-in hybrids are of no use to drivers who don\u2019t have off street parking. They are not going to queue up at public EV chargers, where they will be charged a fortune. Instead, they will simply fill up with petrol and drive it just as like an ordinary car. This will of course make a nonsense of the low emission figures claimed.<\/p>\n\n\n\n

UK ZEV Mandates & Hybrids<\/strong><\/p>\n\n\n\n

The situation in the UK at the moment is that new hybrids can still be sold after 2030, but only subject to ZEV mandates.<\/p>\n\n\n\n

In 2030, fully electric cars must make up at least 80% of sales, leaving 20% for hybrids. However, this hybrid allowance will quickly be cut to the bone, until they are fully phased out in 2035:<\/p>\n\n\n\n

\"Table<\/figure>\n\n\n\n

Hybrid sales this year are running at 25%, so there is realistically no long term future for hybrid manufacturers in this country.<\/p>\n\n\n\n

They will be able to survive for a couple of years or so, taking advantage of extended credit trading (e.g., rewarding CO\u2082 savings from hybrids in earlier years).<\/p>\n\n\n\n

But the outlook after 2030 is bleak, unless the ZEV mandates are completely cancelled, as the Tories have promised.<\/p>\n\n\n\n
