You use the article when you talk about specific cars and you leave out the article when you talk about cars in general. It's the same in English:
We love cars. --> Wir lieben Autos.
We love the cars. --> Wir lieben die Autos.
We love those cars. --> Wir lieben diese Autos.
Most commonly, you will want to say you are interested in cars in general, so you will use "Wir lieben Autos.", but if you for example see a specific car, you can say "Ich liebe das/dieses Auto".
Regarding your second question. "Liebe" (with a capital L) is the noun love. The verb is "lieben" without capital l (to love). In the case of "Wir lieben Autos", "lieben" is the conjugated form of the verb in first person plural.
Ich liebe --> I love
Du liebst --> You love
Er/sie/es liebt --> He/she/it loves
Wir lieben --> We love
Ihr liebt --> You love
Sie lieben --> They love
There are two kinds of articles in German:
Bestimmte Artikel: (definite articles)
Singular:
männlich: der, dessen, dem, den (Nominativ, Genitiv, Dativ, Akkusativ)
weiblich: die, deren, der, die
sächlich: das, dessen, dem, das
Plural:
alle Geschlechter: die, deren, den, die
Unbestimmte Artikel: (indefinite articles)
Singular:
männlich: ein, eines, einem, einen
weiblich: eine, einer, einer, eine
sächlich: ein, eines, einem, ein
Plural:
alle Geschlechter: (-), (-), (-), (-) (void expression in all cases)
In your example you use Akkusativ Plural. The definite article is »ein« and the indefinite article is a void expression (no word). It is exactly the same as in english.
So:
Wir lieben Autos.
Wir lieben (void article) Autos.
Is a sentence where Autos has an indefinite article. So this sentence means:
We love cars.
We love (void article) cars.
Meaning that you love any or some cars. Which cars exactly you love is not determined.
But:
Wir lieben die Autos.
Is a sentence where Autos has an definite article. So this sentence means:
We love the cars.
Meaning that you love a special set of cars. Which set this is must be determined by the context.
With a single sentence such as "Wir lieben die Autos" everybody will be wondering which cars the speaker has in mind, as "die Autos" clearly means a special group of cars. In the sentence "Wir lieben Autos" this is a general statement referring to all cars or any car.
