There is no “concrete plan” to replace the current Honda Accord in the UK, according to company insiders.
Like other cars competing in the cut-throat mainstream D-sector, Accord sales have been hit as drivers are forced by CO2-based taxation to downsize into Golf-class cars.

The rising popularity of compact SUVs is also undermining the European D-sector. UK sales of the Accord have slipped from about 10,000 per year to about 2500.

Importing the Accord from Japan also seriously depresses the car’s profitability because of the strength of the yen against sterling.

Currently, 93 per cent of Honda’s UK sales are of cars made in Britain, resulting in the Accord becoming a niche model alongside the CR-Z and Insight hybrids.
