Chris Macgowan, SMMT chief executive, said: "Stability, certainty and long-term must be the watchwords when changing sensitive tax instruments.
“None appear to have been applied here. Now the uncertainty that followed the collapse of grants for the cleanest vehicles will be mirrored by fears about a budget-by-budget bidding war on road tax changes."
The SMMT also acknowledged the reduction for lower emitting models but said many of the larger family cars and saloons (8% of the UK market) will suffer at the new top rate.
The changes will also bring more administrative pressure to manufacturers and dealers in replacing all colour-coded environmental labels in new car showrooms.
“This comes at a time when manufacturers, dealer staff and consumers are becoming more familiar with this fledgling initiative, designed to give buyers more information about CO2 emissions - and annual running costs - at the point of sale,” said the SMMT.
Macgowan added: “The media focus on VED masks the more serious issue of support for manufacturing. As cost and legislative pressures mount, we heard nothing to help ease costs, reduce the amount of red tape and drive a manufacturing sector accounting for more than 220,000 jobs to a more competitive future.”
