As this superuser answer points out, they actually use ClickOnce to install their download manager:

It actually is ClickOnce.

function installViaClickOnce(opt_navDocument) {
    queueThankyou(10000, '\x26clickonceinstalled=', opt_navDocument);
    downloadInstaller(areStatsEnabled(),
                      _GU_buildClickOncePath,
                      "/update2/installers/clickonce/GoogleInstaller_en.application");
    showThrobber(true);
}

Google's ClickOnce application installs the installer for Chrome which in turn does the download for the browser.
