Diesel demand at auction remains strong
Diesel demand at auction remains strong argues Jayson Whittington, the Chief Car Editor at Glass’s in this industry insight into auction trends
- Glass’s Chief Car Editor, Jayson Whittington (pictured above), adds insight to the increasingly hot topic over diesel demand.
DEMAND remains as strong as ever for diesel cars at auction.
In fact the overall conversion rate in March was slightly above last year’s figure.
It is worth remembering that there are no fiscal penalties associated with owning a diesel car and they remain popular with used retail buyers.
As can be seen in the chart below, there has been a resurgence of interest in petrol models and they have been converting at a slightly faster rate than diesel for most of the last 12 months. That said, diesel cars appear to have been holding their own.

Strong hammer prices
Auction hammer prices have been generally strong so far this year, regardless of fuel type.
This has led to Glass’s values remaining reasonably stable, even strengthening throughout quarter one in the popular ‘Lower Medium’ segment – see chart below.
This shows Glass’s average trade value at three years and 60,000 miles when expressed as a percentage of original cost new price. It shows a comparison of petrol and diesel models. This segment has historically had a fairly equal split of petrol and diesel sales and contains popular volume models such as the Ford Focus and Volkswagen Golf. Petrol models have been outperforming diesel, but rather than suffering a significant downturn in values, diesel has remained consistent.

A similar pattern has emerged in the ‘Premium Upper Medium’ segment which includes models that are popular with fleet operators, such as the Audi A4, BMW 3 Series and Mercedes C-Class. Throughout 2017 the gap between diesel and petrol widened with average diesel residual values reducing by around 1%, but it is worth remembering that the volume of diesel significantly outstrips petrol in this diesel dominated sector, which has resulted in values for the in-demand and undersupplied petrol variants increasing.
Over the past 12 months petrol models have consistently outperformed diesel in virtually all segments. As an example, if we look at the popular ‘Supermini’ segment that contains high volume models such as the Ford Fiesta, it is hardly unsurprising to see petrol outperforming diesel, as petrol tends to be more popular on smaller sized cars.
