I’ve always liked the Mitsubishi logo for it’s simplicity yet it’s effectiveness at conveying a message of confidence in it’s industry. Sharp, clean cut, well designed. Toyota’s suits it because it’s all squished and messy, just like most of their unreliably built Prius cars should be – and I went for a ride in a Celica back in the day and it was the most uncomfortable thing I’d ever sat in, so I think it works well for them – but I don’t like their logo by comparison.
I like Ferrari’s logo because of it’s old school look. It looks almost heraldic and it has a story behind it which I think makes any logo much more significant than it’s made out to be perhaps.
I don’t think I need to supply links to examples to these logos because they are widely used and widely seen.
