"auto*" is not a leading wildcard query, a leading wildcard query would be "*car". Wildcard queries in general will take more time than regular queries, the more close the wildcard is to the first character, the more expensive the query is. With a regular field type, Solr will allow wildcards (not with dismax) like "auto*", but not leading wildcard queries like "*car".
The ReverseWilcardFilter is there for allowing leading wildcards on searches. It only needs to be added at index time (not at query time). When using this field type, all the terms at index time will be reversed like you showed on your example, adding an *impossible character* at the beginning of the term to prevent it to match regular terms. 'autocar' will be indexed as 'autocar' and '#1;racotua' (see '#1;', that's the impossible character). When you search for 'auto*', Solr will resolve the query as always but if you search for '*car', the query parser (not any analysis filter, that's why you don't need to add the filter on query-time) will invert that term and add the 'impossible character' at the beginning, like '#1;rac*'. That's why '#1;racotuar' should match the query. >From your configuration, if you remove the filter at query-time it should work.
