2020 Jeep Wrangler vs 2021 Buick Enclave

It’s hard to find a car with better brand recognition than Jeep's Wrangler. It is an American 4x4 icon, with military roots and millions of miles of trails traversed. As awesome as Jeeps are, they require one caveat: They are not very efficient. This has become more glaring as the rest of the industry works to improve fuel economy. Jeep has made incremental improvements in the past several years, with mild hybrids and turbocharged 4-cylinder engines, but these setups still don‘t get much better than V8-level fuel economy.

So for 2020, Jeep offers a new diesel engine in the Wrangler Unlimited. Read on to learn if this new engine actually improves the Wrangler’s fuel economy. And if not, does the Wrangler Unlimited do other things well enough to make up for its fuel thirstiness?
